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.
