ASP.NET Core 1.1 Hosting - HostForLIFE.eu :: How to Built-In Logging In .NET Core?

clock November 30, 2016 08:19 by author Peter

In this post, I will show you how to Built-In Logging In .NET Core. For an application, logging is very important to keep track of that application and keep it error-free.

In .NET Core, we don't need any third party logging; instead, we can use built-in logging whenever we want. This is very efficient in terms of code and performance. Now, develope a new .NET Core application and name it.

Step 1: Go to Package mManager View-->Other Windows--> Package manager Console  -->

Install-Package Microsoft.Extensions.Logging

Add Logging
Once  the extension's installed, we can add logging by adding ILogger<T> (custom logging) or ILoggerFactory. If we want to use ILoggerFactory, then we must create it using CreateLogger, to use logging add logging services under ConfigureServices. Moreover, we can use built-in logging with the other loggings (like Nlog) with very minimal code.
services.AddLogging(); 

Startup.cs
public class Startup 
    { 
        public Startup(IHostingEnvironment env) 
        { 
            var builder = new ConfigurationBuilder() 
                .SetBasePath(env.ContentRootPath) 
                .AddJsonFile("appsettings.json", optional: true, reloadOnChange: true) 
                .AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true) 
                .AddEnvironmentVariables(); 
            Configuration = builder.Build(); 
        } 
 
        public IConfigurationRoot Configuration { get; } 
 
        // This method gets called by the runtime. Use this method to add services to the container. 
        public void ConfigureServices(IServiceCollection services) 
        { 
            // Add framework services. 
            services.AddMvc(); 
            services.AddLogging(); 
        } 
 
        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline. 
        public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory) 
        { 
            loggerFactory.AddConsole(Configuration.GetSection("Logging")); 
            loggerFactory.AddDebug(); 
 
            if (env.IsDevelopment()) 
            { 
                app.UseDeveloperExceptionPage(); 
                app.UseBrowserLink(); 
            } 
            else 
            { 
                app.UseExceptionHandler("/Home/Error"); 
            } 
 
            app.UseStaticFiles(); 
 
            app.UseMvc(routes => 
            { 
                routes.MapRoute( 
                    name: "default", 
                    template: "{controller=Home}/{action=Index}/{id?}"); 
            }); 
        } 
    } 

ILoggerFactory: We can use  ILoggerFactory. For this, we must use CreateLogger.

_logger = Mylogger.CreateLogger(typeof(HomeController)); 

HomeController.cs
public class HomeController : Controller 
    { 
        private ILogger _logger; 
 
        public HomeController(ILoggerFactory Mylogger) 
        { 
            _logger = Mylogger.CreateLogger(typeof(HomeController)); 
        } 
 
        public IActionResult Index() 
        { 
            return View(); 
        } 
 
        public IActionResult About() 
        { 
            try 
            { 
                ViewData["Message"] = "Your application description page."; 
                _logger.LogInformation("About Page has been Accessed"); 
                return View(); 
            } 
            catch (System.Exception ex) 
            { 
                _logger.LogError("About: " + ex.Message); 
                throw; 
            } 
        } 
 
        public IActionResult Contact() 
        { 
            try 
            { 
                ViewData["Message"] = "Your contact page."; 
                _logger.LogInformation("Contact Page has been Accessed"); 
                return View(); 
            } 
            catch (System.Exception ex) 
            { 
                _logger.LogError("Contact: " + ex.Message); 
                throw; 
            } 
        } 
 
        public IActionResult Error() 
        { 
            return View(); 
        } 
    } 


Run and Test

LogLevel: We can add logging level by adding the level we want in appsettings.json.Trace

  • Debug
  • Information
  • Warning
  • Error
  • Application failure or crashes         


ASP.NET Core 1.1 Hosting - HostForLIFE.eu :: How to Steps To Generate Excel Using EPPlus?

clock November 16, 2016 07:26 by author Peter

My work is to create an excel file, which will contain 3 fields: Address, Latitude and longitude.The user will upload an Address in an excel file and after reading the addresses from an excel file, I have to retrieve Latitude and longitude, using Bing MAP API and build another excel file, which can contain Addresses beside the Latitude and longitude of that address and download the new excel file to the user's end.

Create a MVC Application and add EPPLUS from NuGet package manager to your solution.

Now, Add the code to your .cshtml page.

<h2>Upload File</h2> 
 
sing (Html.BeginForm("Upload", "Home", null, FormMethod.Post, new { enctype = "multipart/form-data" })) 
  { 
      @Html.AntiForgeryToken() 
      @Html.ValidationSummary() 
 
      <div class="form-group"> 
          <input type="file" id="dataFile" name="upload" /> 
      </div> 
 
      <div class="form-group"> 
          <input type="submit" value="Upload" class="btn btn-default" /> 
      </div> 
 
       
  } 


And then, add the code, mentioned below to your controller.

[HttpPost] 
        public ActionResult Upload(HttpPostedFileBase upload) 
        { 
            if (ModelState.IsValid) 
            { 
                if (Path.GetExtension(upload.FileName) == ".xlsx") 
                { 
                    ExcelPackage package = new ExcelPackage(upload.InputStream); 
            //From This part we will read excel file 
                    DataTable dt = ExcelPackageExtensions.ToDataTable(package); 
 
 
                    DataTable dtExcel = new DataTable(); 
                    dtExcel.Columns.Add("Address", typeof(String)); 
                    dtExcel.Columns.Add("LAT", typeof(Double)); 
                    dtExcel.Columns.Add("LONG", typeof(Double)); 
 
                    List<Coordinates> lstCor = new List<Coordinates>(); 
                    for (int i = 0; i < dt.Rows.Count; i++) 
                    { 
                        //Fill the new data Table to generate new excel file 
                    } 
            //This method will generate new excel and download the same 
                    generateExcel(dtExcel);                  
                } 
            } 
            return View(); 
        } 


“ExcelPackageExtensions.ToDataTable(package)” for this create a new class with the name ExcelPackageExtensions and create a static method with the name “ToDataTable()”. The code is mentioned below.

public static class ExcelPackageExtensions 
    { 
        public static DataTable ToDataTable(this ExcelPackage package) 
        { 
            ExcelWorksheet workSheet = package.Workbook.Worksheets.First(); 
            DataTable table = new DataTable(); 
            foreach (var firstRowCell in workSheet.Cells[1, 1, 1, workSheet.Dimension.End.Column]) 
            { 
                table.Columns.Add(firstRowCell.Text); 
            } 
 
            for (var rowNumber = 2; rowNumber <= workSheet.Dimension.End.Row; rowNumber++) 
            { 
                var row = workSheet.Cells[rowNumber, 1, rowNumber, workSheet.Dimension.End.Column]; 
                var newRow = table.NewRow(); 
                foreach (var cell in row) 
                { 
                    newRow[cell.Start.Column - 1] = cell.Text; 
                } 
                table.Rows.Add(newRow); 
            } 
            return table; 
        } 
    } 

Now, add the code part to generate and download an Excel file.
[NonAction] 
        public void generateExcel(DataTable Dtvalue) 
        { 
            string excelpath = ""; 
            excelpath = @"C:\Excels\abc.xlsx";//Server.MapPath("~/UploadExcel/" + DateTime.UtcNow.Date.ToString() + ".xlsx"); 
            FileInfo finame = new FileInfo(excelpath); 
            if (System.IO.File.Exists(excelpath)) 
            { 
                System.IO.File.Delete(excelpath); 
            } 
            if (!System.IO.File.Exists(excelpath)) 
            { 
                ExcelPackage excel = new ExcelPackage(finame); 
                var sheetcreate = excel.Workbook.Worksheets.Add(DateTime.UtcNow.Date.ToString()); 
                if (Dtvalue.Rows.Count > 0) 
                { 
                    for (int i = 0; i < Dtvalue.Rows.Count; ) 
                    { 
                        sheetcreate.Cells[i + 1, 1].Value = Dtvalue.Rows[i][0].ToString(); 
                        sheetcreate.Cells[i + 1, 2].Value = Dtvalue.Rows[i][1].ToString(); 
                        sheetcreate.Cells[i + 1, 3].Value = Dtvalue.Rows[i][2].ToString(); 
                        i++; 
                    } 
                } 
                //sheetcreate.Cells[1, 1, 1, 25].Style.Font.Bold = true; 
                //excel.Save(); 
 
                var workSheet = excel.Workbook.Worksheets.Add("Sheet1"); 
                //workSheet.Cells[1, 1].LoadFromCollection(data, true); 
                using (var memoryStream = new MemoryStream()) 
                { 
                    Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"; 
                    Response.AddHeader("content-disposition", "attachment;  filename=Contact.xlsx"); 
                    excel.SaveAs(memoryStream); 
                    memoryStream.WriteTo(Response.OutputStream); 
                    Response.Flush(); 
                    Response.End(); 
                } 
            } 
 
        }

ASP.NET Core 1.1 Hosting - HostForLIFE.eu :: Uploading File Without PostBack In ASP.NET

clock November 9, 2016 08:55 by author Peter

In this post, you will learn how to upload a file without PostBack in ASP.NET. My main focus to write this blog is that, if you work with file upload control, the page requires full PostBack and if your file upload control is inside the update panel, you must specify your submit button in trigger, as shown below.

 <Triggers> 
    <asp:PostBackTrigger ControlID=""/> 
 </Triggers> 


This also causes the full PostBack problem. To remove this problem, use "Handler" in ASP. NET C#.

UploadFile.ashx Code

 using System; 
 using System.Web; 
 using System.IO; 
 using System.Web.SessionState; 
 public class UploadFile: IHttpHandler, IRequiresSessionState { 
     public void ProcessRequest(HttpContext context) { 
         string filedata = string.Empty; 
         if (context.Request.Files.Count > 0) { 
             HttpFileCollection files = context.Request.Files; 
             for (int i = 0; i < files.Count; i++) { 
                 HttpPostedFile file = files[i]; 
                 if (Path.GetExtension(file.FileName).ToLower() != ".jpg" && 
                     Path.GetExtension(file.FileName).ToLower() != ".png" && 
                     Path.GetExtension(file.FileName).ToLower() != ".gif" && 
                     Path.GetExtension(file.FileName).ToLower() != ".jpeg" && 
                     Path.GetExtension(file.FileName).ToLower() != ".pdf" 
                 ) { 
                     context.Response.ContentType = "text/plain"; 
                     context.Response.Write("Only jpg, png , gif, .jpeg, .pdf are allowed.!"); 
                     return; 
                 } 
                 decimal size = Math.Round(((decimal) file.ContentLength / (decimal) 1024), 2); 
                 if (size > 2048) { 
                     context.Response.ContentType = "text/plain"; 
                     context.Response.Write("File size should not exceed 2 MB.!"); 
                     return; 
                 } 
                 string fname; 
                 if (HttpContext.Current.Request.Browser.Browser.ToUpper() == "IE" || HttpContext.Current.Request.Browser.Browser.ToUpper() == "INTERNETEXPLORER") { 
                     string[] testfiles = file.FileName.Split(new char[] { 
                         '\\' 
                     }); 
                     fname = testfiles[testfiles.Length - 1]; 
                 } else { 
                     fname = file.FileName; 
                 } 
                 //here UploadFile is define my folder name , where files will be store. 
                 string uploaddir = System.Configuration.ConfigurationManager.AppSettings["UploadFile"]; 
                 filedata = Guid.NewGuid() + fname; 
                 fname = Path.Combine(context.Server.MapPath("~/" + uploaddir + "/"), filedata); 
                 file.SaveAs(fname); 
             } 
         } 
         context.Response.ContentType = "text/plain"; 
         context.Response.Write("File Uploaded Successfully:" + filedata + "!"); 
         //if you want to use file path in aspx.cs page , then assign it in to session 
         context.Session["PathImage"] = filedata; 
     } 
     public bool IsReusable { 
         get { 
             return false;

     }

European ASP.NET Core 1.0 Hosting - HostForLIFE.eu :: How to Publish Your ASP.NET Core in IIS

clock November 3, 2016 09:27 by author Scott

When you build ASP.NET Core applications and you plan on running your applications on IIS you'll find that the way that Core applications work in IIS is radically different than in previous versions of ASP.NET.

In this post I'll explain how ASP.NET Core runs in the context of IIS and how you can deploy your ASP.NET Core application to IIS.

Setting Up Your IIS and ASP.NET Core

The most important thing to understand about hosting ASP.NET Core is that it runs as a standalone, out of process Console application. It's not hosted inside of IIS and it doesn't need IIS to run. ASP.NET Core applications have their own self-hosted Web server and process requests internally using this self-hosted server instance.

You can however run IIS as a front end proxy for ASP.NET Core applications, because Kestrel is a raw Web server that doesn't support all features a full server like IIS supports. This is actually a recommended practice on Windows in order to provide port 80/443 forwarding which kestrel doesn't support directly. For Windows IIS (or another reverse proxy) will continue to be an important part of the server even with ASP.NET Core applications.

Run Your ASP.NET Core Site

To run your ASP.NET Core site, it is quite different with your previous ASP.NET version. ASP.NET Core runs its own web server using Kestrel component. Kestrel is a .NET Web Server implementation that has been heavily optimized for throughput performance. It's fast and functional in getting network requests into your application, but it's 'just' a raw Web server. It does not include Web management services as a full featured server like IIS does.

If you run on Windows you will likely want to run Kestrel behind IIS to gain infrastructure features like port 80/443 forwarding via Host Headers, process lifetime management and certificate management to name a few.

ASP.NET Core applications are standalone Console applications invoked through the dotnet runtime command. They are not loaded into an IIS worker process, but rather loaded through a native IIS module called AspNetCoreModule that executes the external Console application.

Once you've installed the hosting bundle (or you install the .NET Core SDK on your Dev machine) the AspNetCoreModule is available in the IIS native module list:

The AspNetCoreModule is a native IIS module that hooks into the IIS pipeline very early in the request cycle and immediately redirects all traffic to the backend ASP.NET Core application. All requests - even those mapped to top level Handlers like ASPX bypass the IIS pipeline and are forwarded to the ASP.NET Core process. This means you can't easily mix ASP.NET Core and other frameworks in the same Site/Virtual directory, which feels a bit like a step back given that you could easily mix frameworks before in IIS.

While the IIS Site/Virtual still needs an IIS Application Pool to run in, the Application Pool should be set to use No Managed Code. Since the App Pool acts merely as a proxy to forward requests, there's no need to have it instantiate a .NET runtime.

The AspNetCoreModule's job is to ensure that your application gets loaded when the first request comes in and that the process stays loaded if for some reason the application crashes. You essentially get the same behavior as classic ASP.NET applications that are managed by WAS (Windows Activation Service).

Once running, incoming Http requests are handled by this module and then routed to your ASP.NET Core application.

So, requests come in from the Web and int the kernel mode http.sys driver which routes into IIS on the primary port (80) or SSL port (443). The request is then forwarded to your ASP.NET Core application on the HTTP port configured for your application which is not port 80/443. In essence, IIS acts a reverse proxy simply forwarding requests to your ASP.NET Core Web running the Kestrel Web server on a different port.

Kestrel picks up the request and pushes it into the ASP.NET Core middleware pipeline which then handles your request and passes it on to your application logic. The resulting HTTP output is then passed back to IIS which then pushes it back out over the Internet to the HTTP client that initiated the request - a browser, mobile client or application.

The AspNetCoreModule is configured via the web.config file found in the application's root, which points a the startup command (dotnet) and argument (your application's main dll) which are used to launch the .NET Core application. The configuration in the web.config file points the module at your application's root folder and the startup DLL that needs to be launched.

Here's what the web.config looks like:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <!--
    Configure your application settings in appsettings.json. Learn more at http://go.microsoft.com/fwlink/?LinkId=786380
  -->
  <system.webServer>
    <handlers>
      <add name="aspNetCore" path="*" verb="*"
        modules="AspNetCoreModule" resourceType="Unspecified" />
    </handlers>
    <aspNetCore processPath="dotnet"
                arguments=".\AlbumViewerNetCore.dll"
                stdoutLogEnabled="false"
                stdoutLogFile=".\logs\stdout"
                forwardWindowsAuthToken="false" />
  </system.webServer>
</configuration>

You can see that module references dotnetexe and the compiled entry point DLL that holds your Main method in your .NET Core application.

IIS is Recommended!

We've already discussed that when running ASP.NET Core on Windows, it's recommended you use IIS as a front end proxy. While it's possible to directly access Kestrel via an IP Address and available port, there are number of reasons why you don't want to expose your application directly this way in production environments.

First and foremost, if you want to have multiple applications running on a single server that all share port 80 and port 443 you can't run Kestrel directly. Kestrel doesn't support host header routing which is required to allow multiple port 80 bindings on a single IP address. Without IIS (or http.sys actually) you currently can't do this using Kestrel alone (and I think this is not planned either).

The AspNetCoreModule running through IIS also provides the necessary process management to ensure that your application gets loaded on the first access, ensures that it stays up and running and is restarted if it crashes. The AspNetCoreModule provides the required process management to ensure that your AspNetCore application is always available even after a crash.

It's also a good idea to run secure SSL requests through IIS proper by setting up certificates through the IIS certificate store and letting IIS handle the SSL authentication. The backplane HTTP request from IIS can then simply fire a non-secure HTTP request to your application. This means only a the front end IIS server needs a certificate even if you have multiple servers on the backplane serving the actual HTTP content.

IIS can also provide static file serving, gzip compression of static content, static file caching, Url Rewriting and a host of other features that IIS provides natively. IIS is really good and efficient at processing non-application requests, so it's worthwhile to take advantage of that. You can let IIS handle the tasks that it's really good at, and leave the dynamic tasks to pass through to your ASP.NET Core application.

The bottom line for all of this is if you are hosting on Windows you'll want to use IIS and the AspNetCoreModule.

How to Publish ASP.NET Core in IIS

In order to run an application with IIS you have to first publish it. There are two ways to that you can do this today:

1. Use dotnet publish

Using dotnet publish builds your application and copies a runnable, self-contained version of the project to a new location on disk. You specify an output folder where all the files are published. This is not so different from classic ASP.NET which ran Web sites out of temp folders. With ASP.NET Core you explicitly publish an application into a location of your choice - the files are no longer hidden away and magically copied around.

A typical publish command may look like this:

dotnet publish
      --framework netcoreapp1.0
      --output "c:\temp\AlbumViewerWeb"
      --configuration Release

If you open this folder you'll find that it contains your original application structure plus all the nuget dependency assemblies dumped into the root folder:

Once you've published your application and you've moved it to your server (via FTP or other mechanism) we can then hook up IIS to the folder.

After that, please just make sure you setup .NET Runtime to No Managed Code as shown above.

And that's really all that needs to happen. You should be able to now navigate to your site or Virtual and the application just runs.

You can now take this locally deployed Web site, copy it to a Web Server (via FTP or direct file copy or other publishing solution), set up a Site or Virtual and you are off to the races.

2. Publish Using Visual Studio

The dotnet publish step works to copy the entire project to a folder, but it doesn't actually publish your project to a Web site (currently - this is likely coming at a later point).

In order to get incremental publishing to work, which is really quite crucial for ASP.NET Core applications because there are so many dependencies, you need to use MsDeploy which is available as part of Visual Studio's Web Publishing features.

Currently the Visual Studio Tooling UI is very incomplete, but the underlying functionality is supported. I'll point out a few tweaks that you can use to get this to work today.

When you go into Visual Studio in the RC2 Web tooling and the Publish dialog, you'll find that you can't create a publish profile that points at IIS. There are options for file and Azure publishing but there's no way through the UI to create a new Web site publish.

However, you can cheat by creating your own .pubxml file and putting it into the \Properties\PublishProfilesfolder in your project.

To create a 'manual profile' in your ASP.NET Core Web project:

  • Create a folder \Properties\PublishProfiles
  • Create a file <MyProfile>.pubxml

You can copy an existing .pubxml from a non-ASP.NET Core project or create one. Here's an example of a profile that works with IIS:

<Project ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <PropertyGroup>
    <WebPublishMethod>MSDeploy</WebPublishMethod>
    <LastUsedBuildConfiguration>Release</LastUsedBuildConfiguration>
    <LastUsedPlatform>Any CPU</LastUsedPlatform>
    <SiteUrlToLaunchAfterPublish>http://samples.west-wind.com/AlbumViewerCore/index.html</SiteUrlToLaunchAfterPublish>
    <LaunchSiteAfterPublish>True</LaunchSiteAfterPublish>
    <ExcludeApp_Data>False</ExcludeApp_Data>
    <PublishFramework>netcoreapp1.0</PublishFramework>
    <UsePowerShell>True</UsePowerShell>
    <EnableMSDeployAppOffline>True</EnableMSDeployAppOffline>
    <MSDeployServiceURL>https://publish.west-wind.com</MSDeployServiceURL>
    <DeployIisAppPath>samples site/albumviewercore</DeployIisAppPath>
    <RemoteSitePhysicalPath />
    <SkipExtraFilesOnServer>True</SkipExtraFilesOnServer>
    <MSDeployPublishMethod>RemoteAgent</MSDeployPublishMethod>
    <EnableMSDeployBackup>False</EnableMSDeployBackup>
    <UserName>username</UserName>
    <_SavePWD>True</_SavePWD>
    <ADUsesOwinOrOpenIdConnect>False</ADUsesOwinOrOpenIdConnect>
    <AuthType>NTLM</AuthType>
  </PropertyGroup>
</Project>

Once you've created a .pubxml file you can now open the publish dialog in Visual Studio with this Profile selected:

At this point you should be able to publish your site to IIS on a remote server and use incremental updates with your content.

#And it's a Wrap Currently IIS hosting and publishing is not particularly well documented and there are some rough edges around the publishing process. Microsoft knows of these issues and this will get fixed by RTM of ASP.NET Core.

In the meantime I hope this post has provided the information you need to understand how IIS hosting works and a few tweaks that let you use the publishing tools available to get your IIS applications running on your Windows Server.

European ASP.NET Core 1.0 Hosting - HostForLIFE.eu :: Setup Angular 2 in ASP.NET Core 1.0

clock October 12, 2016 00:11 by author Scott

This tutorial aims for starting Angular 2 in ASP.NET Core using Visual Studio 2015. The release of Angular 2, ASP.NET Core RC is becoming interesting to build SPA.

I have compiled the steps involved in starting to learn Angular 2. This is detailed explanation, you will feel much easier at end of article.

Create Your ASP.NET Core Project

Open Visual Studio 2015 Community Edition Update 3, Select New Web Project naming it “ngCoreContacts” and select “Empty” project template. Don’t forget to install new web tools for ASP.NET Core 1.0

I used Visual Studio 2015 Community Edition Update 3(Must update), TypeScript 2.0 (must), latest NPM, Gulp.

Setup ASP.NET Core to Serve Static Files

ASP.NET Core is designed as pluggable framework to include and use only necessary packages, instead of including too many initial stuff.

Lets create HTML file named “index.html” under wwwroot folder.

Right click on wwwroot folder, Add New Item and create index.html file. This HTML page will act as default page.

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8" />
    <title>Angular 2 with ASP.NET Core</title>
</head>
<body>
    <h1>Demo of Angular 2 using ASP.NET Core with Visual Studio 2015</h1>
</body>
</html>

For ASP.NET Core to serve static files, we need to add StaticFiles middle ware in Configure method of Startup.cs page. Ensure that packages are restored properly.

project.json is redesigned to make it better, we have Static Files middleware to serve static assets like HTML, JS files etc.

public void Configure(IApplicationBuilder app)
        {
            app.UseDefaultFiles();
            app.UseStaticFiles();
        }

 

{
  "dependencies": {
    "Microsoft.NETCore.App": {
      "version": "1.0.1",
      "type": "platform"
    },
    "Microsoft.AspNetCore.Diagnostics": "1.0.0",
    "Microsoft.AspNetCore.Server.IISIntegration": "1.0.0",
    "Microsoft.AspNetCore.Server.Kestrel": "1.0.1",
    "Microsoft.Extensions.Logging.Console": "1.0.0",
    "Microsoft.AspNetCore.StaticFiles": "1.0.0"
  },

  "tools": {
    "Microsoft.AspNetCore.Server.IISIntegration.Tools": "1.0.0-preview2-final"
  },

  "frameworks": {
    "netcoreapp1.0": {
      "imports": [
        "dotnet5.6",
        "portable-net45+win8"
      ]
    }
  },

  "buildOptions": {
    "emitEntryPoint": true,
    "preserveCompilationContext": true,
    "compile": {
      "exclude": [ "node_modules" ]
    }
  },

  "runtimeOptions": {
    "configProperties": {
      "System.GC.Server": true
    }
  },

  "publishOptions": {
    "include": [
      "wwwroot",
      "web.config"
    ]
  },

  "scripts": {   
    "postpublish": [ "dotnet publish-iis --publish-folder %publish:OutputPath% --framework %publish:FullTargetFramework%" ]
  }
}

Run the application now, ASP.NET Core renders static HTML page.

Delete this index.html page, we will be injecting this dynamically later. Till now you saw demonstration of “wwwroot“ as root folder for ASP.NET Core web apps.

Setup Angular 2 in ASP.NET Core

Angular 2 is famously claiming to be ONE Framework for MOBILE and DESKTOP apps. There’s won’t be any breaking changes after final release.

This tutorial refers 5 MIN QUICK START for getting started, it’s more focused on other light weight code editors; but here we are using Visual Studio 2015 Community Edition Update 3 for its built in TypeScript tooling and other features.

We will be using Webpack for module bundler, it’s an excellent alternative to the systemJS approach. To know more about inner details of read “webpack and Angular 2

Majority of webpack scripting is based on AngularClass’s angular2-webpack-starter. I have modified according to ASP.NET Core web apps.

Adding NPM Configuration file for Angular 2 Packages

Angular 2 team is pushing the code changes using NPM rather than CDN or any other source, due to this we need to add NPM configuration file (package.json) to this ASP.NET Core application.

Right Click on “ngCoreContacts“, add new file “NPM Configuration File“; by default package.json is added to ASP.NET Core project. This acts Node Package Manager (NPM) file, a must for adding packages for Angular 2

From the Angular 2 Quick start provided above, we need to add dependencies for required for Angular 2 in ASP.NET Core application. Copy Paste below configuration in package.json file

{
    "version": "1.0.0",
    "description": "ngcorecontacts",

    "webpack-md5-hash": "^0.0.5",
    "webpack-merge": "^0.14.1"
  }
}

Right after saving this, ASP.NET Core starts restoring the packages. It would download all packages mentioned independencies section of above package.json.

Sometimes in solution explorer you might see ‘Dependencies – not installed’, don’t worry this bug in tooling. All the npm packages are installed.

Add TypeScript configuration file – must for Angular 2 in ASP.NET Core using TypeScript

We are creating Angular 2 in ASP.NET Core starting with TypeScript, this obvious reason adds to include TypeScript Configuration file which does work of transpiling it to JavaScript, module loading, target ES5 standards.

Add “tsconfig.json” in the project, copy paste below configuration.

{
  "compilerOptions": {
    "target": "es5",
    "module": "commonjs",
    "moduleResolution": "node",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "allowSyntheticDefaultImports": true,
    "sourceMap": true,
    "noEmitHelpers": true,
    "strictNullChecks": false,
    "baseUrl": "./clientsrc",
    "paths": [],
    "lib": [
      "dom",
      "es6"
    ],
    "types": [
      "hammerjs",     
      "node",     
      "source-map",
      "uglify-js",
      "webpack"
    ]
  },
  "exclude": [
    "node_modules",
    "dist"
  ],
  "awesomeTypescriptLoaderOptions": {
    "forkChecker": true,
    "useWebpackText": true
  },
  "compileOnSave": false,
  "buildOnSave": false,
  "atom": { "rewriteTsconfig": false }
}

It’s mandatory to install TypeScript 2.o for working with Angular 2.

At present typings.json is not required because we are using @types with TypeScript. However if your using any other packages which don’t have entries in @types then typings.json has to be added.

Use Webpack as Module Bundler

Webpack is a powerful module bundler. A bundle is a JavaScript file that incorporate assets that belong together and should be served to the client in a response to a single file request. A bundle can include JavaScript, CSS styles, HTML, and almost any other kind of file.

Webpack roams over your application source code, looking for import statements, building a dependency graph, and emitting one (or more) bundles. With plugin “loaders” Webpack can preprocess and minify different non-JavaScript files such as TypeScript, SASS, and LESS files.

In package.json, we have added “webpack“ packages as “devdependencies“. They will perform all bundling work.

What webpack does is written in a JavaScript configuration file know as webpack.config.js. As always the applications are run in Development, Test and Production environment.

There are some common functionalities and some specific to environments. We will focus on development and productionenvironment to write accordingly.

Development environment should have source maps for debugging TypeScript files, minifying bundles of JS, CSS etc files not necessary.

Production environment should minify bundles to reduce loading time, do not include source maps. Webpack 2 also does tree shaking i.e. eliminate unused code to further reduce bundle sizes.

webpack.config.js – Based on environment set process.env.NODE_ENV, it runs either dev or prod configurations.

Webpack.common.js before bundling environment specific files, it performs tasks meant to be used for both environment.

  • Webpack splits Angular 2 apps into 3 files polyfills(to maintain backward compatibility with older browsers) , vendors(all JS, CSS, HTML, SCSS, images, JSON etc into one file) and boot (application specific files)
  • resolve based on various file extensions
  • Webpack itself doesn’t know what to do with a non-JavaScript file. We teach it to process such files into JavaScript withloaders. For this, we have written loaders TS, HTML, JSON, Fonts, images
  • Any static assets placed in “clientsrc/assets” will be copied to assets folder using CopyWebpackPlugin
  • CleanWebpackPlugin cleans “wwwroot/dist” folder every time we run it, so that we get fresh set of files.
  • I told you above to delete the index.html file, now the clientsrc/index.html will be moved to wwwroot usingHtmlWebpackPlugin. Plus Webpack injects the bundle files i.e. polyfills, vendor, boot JS files and includes them in HTML script reference.

Now let’s see webpack.dev.js for development purpose

  • Running “webpack-dev-server” – this runs entire application in memory, any changes to source file gets applied immediately
  • Loads application in debug mode with source map. Everything run in memory i.e. html, js, static files are loaded in memory.
  • Runs the application on localhost 3000 port. Port can be changed as your convenience

Now let’s see webpack.prod.js for production purpose

  • Merges all the bundle files and copies to wwwroot.
  • Minifies all files to load faster using UglifyJsPlugin plugin

Writing Angular 2 application

Until now we created ASP.NET Core app, added TSconfig file, webpack configuration. Now it’s time to write Angular 2 application

In the github repo, you can see “clientsrc” folder. This contains the angular 2 app which gets bundled into using webpack configurations we wrote

“Clientsrc“ folder has index.html, polyfills.browses.ts, vendor.browsers.ts and mostly importantly boot.ts

We have app folder containing HTML, Angular 2 components and root level module (app.module.ts) which gets loaded while bootstrapping application.

Some of files might be not interesting now, will focus them in separate articles later.

Running the application

Before running make sure you have run command “npm install”. This might not be needed but still it will ensure all packages are installed.

Now let’s run the application in development mode

  • From command line (directory should be same as package.json), type “npm start” & hit enter. It will start running the webpack-dev-server which loads application and listens on localhost:3000.
  • When on console it says “bundle is now VALID” then open a browser and navigate to http://localhost:3000 to see application getting loaded.

Notice wwwroot folder, we don’t see any files copied because everything is running in memory.

Now that application runs properly on browser, let’s understand how Angular 2 app loads

  • When browser starts rendering index.html page, it encounters <my-app>Loading…</my-app> tag.
  • Then Angular’s module platformBrowserDynamic bootstraps clientsrc/app/AppModule through lineplatformBrowserDynamic().bootstrapModule(AppModule)
  • AppModule then loads the component app.component.ts which is mentioned in @NgModule as bootstrap entry
  • Clientsrc/src/Appcomponent then resolves the <my-app> tag as selector in it and renders UI with TypeScript code.

When we enter “npm start” in console to run the application, execution points scripts section of package.json to below code

webpack-dev-server --config config/webpack.dev.js --progress --profile --watch --content-base clientsrc/

This invokes webpack-dev-server, runs the development config and watches for any changes in clientsrc folder. Any changes in this folder will reload application with changes.

Running the application in Production mode

Assuming the application is now ready to deployed, we need to have PROD build. For this run command

//builds app and copies in wwwroot
Npm run build:prod

Now if you see wwwroot folder, we see the HTML, JS bundle files. This wwwroot folder can be deployed on any web server like IIS or nginx

You can either do F5 to run from Visual Studio IDE or run command npm run server:prod

European ASP.NET Core Hosting - HostForLIFE.eu :: How to Fix Error 502.5 - Process Failure in ASP.NET Core

clock October 4, 2016 19:35 by author Scott

This is an issue that sometimes you face when you deploying your ASP.NET Core on shared hosting environment.

Problem

HTTP Error 502.5 - Process Failure

Common causes of this issue:

* The application process failed to start
* The application process started but then stopped
* The application process started but failed to listen on the configured port

Although your hosting provider have setup .net core for you, you can face error above. So, how to fix this problems?

Solution

There are 2 issues that cause the above error

#1. Difference ASP.NET Core Version

1. The difference ASP.NET Core version. Microsoft just released newest ASP.NET Core 1.0.1. Maybe you are still using ASP.NET Core 1.0. So, you must upgrade your .net Core version.

2. When you upgraded your app, make sure that your ‘Microsoft.NETCoreApp’ setting in your project.json was changed to:

"Microsoft.NETCore.App": "1.0.1",

3. Fixing your App ‘type’

"Microsoft.NETCore.App": { "version": "1.0.1", "type": "platform" },

#2. Set path to dotnet.exe in the web.config

Here is example to change your web.config file:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <!--
    Configure your application settings in appsettings.json. Learn more at https://go.microsoft.com/fwlink/?LinkId=786380
  -->
  <system.webServer>
    <handlers>
      <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModule" resourceType="Unspecified" />
    </handlers>
    <aspNetCore processPath="C:\Program Files\dotnet\dotnet.exe" arguments=".\CustomersApp.dll" stdoutLogEnabled="true" stdoutLogFile=".\logs\stdout" forwardWindowsAuthToken="false" />
  </system.webServer>

In this code snippet, we learn how to get selected value, selected index and selected of asp dropdownlist in JavaScript. First, Create new web application in visual studio.
Now, Add one webform to application. In this tutorial we added WebForm1 in application. And Then Add on DropDownList control to webform. Design webform as follows:

<%@ Page Language="C#" AutoEventWireup="true"CodeBehind="WebForm1.aspx.cs" Inherits="DropDownListJS.WebForm1" %> 
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN""http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
<html xmlns="http://www.w3.org/1999/xhtml"> 
<head runat="server"> 
<title></title> 
<script type="text/javascript"> 
function GetListDetails() { 
    var param = document.getElementById('ddlColors'); 
    document.getElementById('lblText').innerHTML = param.options[param.selectedIndex].text; 
    document.getElementById('lblValue').innerHTML = param.options[param.selectedIndex].value; 
    document.getElementById('lblIndex').innerHTML = param.options[param.selectedIndex].index; 

</script> 
</head> 
<body> 
<form id="form1" runat="server"> 
<div> 
    <table> 
        <tr> 
            <td> 
                Colors 
            </td> 
            <td> 
                <asp:DropDownList ID="ddlColors" runat="server" onchange="GetListDetails()"> 
                    <asp:ListItem Text="Select" Value="0" /> 
                    <asp:ListItem Text="Red" Value="11" /> 
                    <asp:ListItem Text="Green" Value="22" /> 
                    <asp:ListItem Text="Blue" Value="33" /> 
                </asp:DropDownList> 
            </td> 
        </tr> 
        <tr> 
            <td> 
                Selecte Index :
            </td> 
            <td> 
                <label id="lblIndex">

            </td> 
        </tr> 
        <tr> 
            <td> 
                Selecte Text : 
            </td> 
            <td> 
                <label id="lblText">

            </td> 
        </tr> 
        <tr>

                </label> 
            </td> 
        </tr> 
    </table> 
</div>
</form> 
</body> 
</html>
