European ASP.NET 4.5 Hosting - Amsterdam :: Windows Identity Foundation 4.5 in NET 4.5

clock October 16, 2013 12:03 by author Scott

Windows Identity Foundation 4.5 (WIF) is a framework for building identity-aware and more specifically claims-aware applications. It furthermore provides an abstraction  to the underlying protocols (ex: WS-Trust, WS-Federation, etc …) and therefore encapsulates and standardizes application security.

Developers do not need to know how to exactly implement and use those protocols anymore. Instead they may use API calls to the WIF Toolkit for implementing secure applications, thus resulting in applications which are loosely coupled to their security implementations. Tokens issued from a large scale of different security providers (including  ADFS 2.0, ACS and custom Security Token Services) can be handled.

The default configuration and behavior works great and with ease you will be able to implement it in no time. But the best of all : the WIF Toolkit is highly customizable. You may completely override and customize the default behavior on some or on all the step of the process (Protocol Module, Session Module, Claims Authorization Module, Token, STS, etc..).

WIF in its first version (1.0) is available as a runtime and as an external SDK for .NET 3.5 and .NET 4.0. You have to install it separately for being able to using it in your applications. The WIF Training Kit contains everything necessary to start with claims based security (explication, tutorials, examples, etc…).

WIF 4.5 and .NET 4.5

So what’s new in WIF 4.5 ? Well first of all WIF is now part of the .NET framework. You do not need to install it manually anymore. It is shipped and installed with .NET 4.5, which means that it is now an integral part of the framework ! Most of the classes and methods are now part of Mscorlib.dll !

Also it is now much easier and straightforward use WIF and to query for claims. Let me show this in the following example.

Create a new web application, right click on your project in the Solution Explorer and select "Identity and Access…” from the list.

You will see a new configuration wizard, which will guide you through the process of setting up a STS reference. You may either use a development STS, a business provider based on ADFS2 or Windows Azure Access Control Service (ACS).

For the example I use the development STS :

You may now run your web application and the development STS gets started automatically. When you see the little icon in the tray area you know that everything working correctly.

Now lets see how to query for a claim by using the ClaimsPrincipal in the System.Security.Claims namespace and calling its FindFirst(…) method.

Where you had to write at least 3 lines of code and do casting operations in WIF 1.0, you now have everything in a single line ! Much easier to implement, to understand, to maintain and also to extend !

Note that there are a variety of other utility methods to aid you in working with claims (FindAll, FindFirst, HasClaim, etc…) and that you have access to almost everything just by using the  ClaimsPrincipal.

Another improvement is the seamless integration of WCF 4.5 and WIF 4.5. You now can use both together much more easily. Custom service host factories or federation behaviors are not needed anymore. This can be achieved via the useIdentityConfiguration switch.

WIF 4.5 and WebFarms

Great news for all developers using WIF in a WebFarms environment. With .NET 4.5 it is finally possible to use WIF without implementing complicated and time consuming workarounds to encrypt your WIF cookies with a single encryption key.

You just configure a new MachineSessionSecurityHandler by setting it in your Web.config file and it will work without any further changes ! This has even been added to the wizard as a checkbox! How easy is that compared to the old way of resolving this problem !

WIF 4.5 and Windows Server 2012

Windows Server 2012 Domain Controllers are going to support the claims based model and provide extra claims via Kerberos (User Claims and Device Claims), which you may then query for within your WIF 4.5 implementations. This is actually a quite interesting feature.

WIF 4.5 and Visual Studio 2012

The integration of WIF tools has been completely re-designed, as you saw in my quick example above. This has been done to simplify the whole process and to render it much more comprehensive. So it is now easier to understand with less steps and quicker configuration.

As you saw above the new tools contain a local development STS which simulates a real STS (comparable to the development fabric within the Windows Azure SDK). The development STS is by the way completely configurable (Token format, port, test claims, etc..).

Furthermore, the WIF 4.5 tools and all samples are now distributed as VSIX via the Visual Studio Extensions Gallery.


As you can see WIF 4.5 has been greatly enhanced and industrialized. It will become the the primary choice when working with application security. Come on and give it at try,  test all these new features by downloading the Windows Identity Foundation Tools for Visual Studio 2012 RC.

European ASP.NET 4.5 Hosting - Amsterdam :: How to Upload Multiple Files Using FileUpload Control in ASP.NET 4.5

clock October 1, 2013 10:42 by author Scott

Here I will discuss with you one of them, the feature of new the FileUpload control in ASP.NET 4.5. The FileUpload control in ASP.NET extends it's functionality by supporting the upload of multiple files at once.

Prior to this latest version, the FileUpload control only supported a single file at a time, but version ASP.NET version 4.5 solves this issue very well.

Now, the FileUpload control is built to support HTML 5, therefore it is only supported in browsers supporting HTML5. For other browsers it will work like a normal file upload control in ASP.NET.

A new attribute that comes with the ASP.NET 4.5 FileUplaod control is that:

AllowMultiple: It takes either true or false.

In order to support multiple file uploads, set AllowMulitple="true" other than false.

This attribute is for the browsers that support multiple files to be uploaded and for this purpose it renders the necessary HTML5 attribute.

In addition to this control, some new properties have been included to support code-behind coding.

HasFiles: Check whether FileUpload control has multiple files or not.

PostedFiles: Basically used to get all the files from the FileUpload control in the iteration.

Both properties will help to work with the mulitple selected files in Code-Behind coding (C#).

After the preceding overview of the theory, let's proceed to implement this cool feature in an application.

First, in the ASPX page declare a FileUpload control.

Remember: Set the AllowMultiple attribute to "true" to enable the multiple file upload feature.

<asp:FileUpload runat="server" ID="UploadImages" AllowMultiple="true" />

Now, the following HTML is rendered in the browser:

<input type="file" multiple="multiple" name="FileUpload1" id="FileUpload1" />

The AllowMultiple attribute renders multiple attributes in the HTML 5.

The complete code for .aspx file will looks like:

    <asp:FileUpload runat="server" ID="UploadImages" AllowMultiple="true" />
    <asp:Button runat="server" ID="uploadedFile" Text="Upload" OnClick="uploadFile_Click" />
    <asp:Label ID="listofuploadedfiles" runat="server" />

You will see that I have attached a button's click event. So, now start to write C# for this.

In the following code I will use HasFiles and PostedFiles properties that we will see in the preceding section.

protected void uploadFile_Click(object sender, EventArgs e)
   if (UploadImages.HasFiles)
       foreach (HttpPostedFile uploadedFile in UploadImages.PostedFiles)
           uploadedFile.FileName)); listofuploadedfiles.Text += String.Format("{0}<br />", uploadedFile.FileName);

In the code above I have saved each image in the Images folder of the web application from the PostedFiles collection.

Now, run the application and see the output.

Select multiple files and click on the Upload button and it will show you the list of files that have been uploaded.
