Where is System.ServiceModel.Web.dll?

Question

I am developing a Windows service that exposes a WCF service intended to be consumed by a Silverlight application, as explained in this blog post: http://mtaulty.com/CommunityServer/blogs/mike_taultys_blog/archive/2008/03/27/10291.aspx

The problem I am facing is that I need to use the WebInvoke attribute, which is defined in the System.ServiceModel.Web.dll assembly, but when I try to add a reference to that assembly in the project (by using Visual Studio's Add Reference dialog - .NET tab), there is no assembly with that name.

So, am I doing something wrong, this assembly is not part of the standard .NET Framework, or it is a bug in Visual Studio? By the way I'm using VS2010 beta 2 and the project targets .NET Framework 4.

Was it helpful?

Solution

Are you targetting .NET4 Full or Client Profile? The latter does not include the System.ServiceModel.Web assembly.

OTHER TIPS

Apparently when you select .NET framework 4.0 while creating the project, Visual Studio 2010 Beta 2 actually targets .NET framework 4 client profile. Change the target framework to .NET framework 4 using project properties.

Please look at the following folder for System.ServiceModel.Web.dll

C:\Program Files\Reference Assemblies\Microsoft\Framework.NETFramework\v4.0\

I use Visual Web Developer and facing the same issue. My project is already configured targetting .Net 4.0 Framework. The solution for my case is adding reference to my my project by :

right click on References, choose Add Reference and find System.ServiceModel.Web under .Net Tab

Check your project properties and on the Application tab make sure you have selected the full ".NET FRAMEWORK" and not ".NET FRAMEWORK CLIENT PROFILE" in the target framework combo.

You can find the configuration with the below steps.

  1. Right Click Project in Solution Explorer

  2. Choose Properties

  3. Choose Compile TAB on the left

  4. At the end of the compile page click Advanced Compile Option*s Button, this will bring up the A*dvanced Compiler Settings

  5. The last control is a drop down reading "Target framework (all configurations)

Add the following reference to your project 

System.ServiceModel.Web.dll

If you are not able to find System.ServiceModel.Web in - 'Add Reference' click on Component Name to sort the list.
