How to debug incompatibility between .NET RIA Servces (July Preview) and Silverlight MVVM toolkit?

Question

I have discovered that when I install .NET RIA Services (July preview) it breaks all of my projects that were created with Michael Sync's Silverlight MVVM toolkit.

This MVVM toolkit includes a Visual Studio project template which is now failing to build. Here is the message I get:

The project file "..\SilverlightModelViewApplication.Web\SilverlightModelViewApplication.Web.csproj" was not found.

I don't find the string "SilverlightModelViewApplication" anywhere in the solution. I get the same message if I create an empty new project using the template. If I uninstall .NET RIA Services with Programs & Features, my MVVM projects build successfully; when I reinstall .NET RIA Services my projects fail to build again.

How can I debug this? I posted a comment on the MVVM toolkit site but there has been no response. Thanks!

This question was answered on the MS Silverlight forum by MS engineer Brett Samblanet.

Short-term fix: Turn off the RIA Service link to "SilverlightModelViewApplication.Web.csproj" in the .web project properties.

Long-term fix: Change the MVVM template .csproj file entry for <LinkedServerProject> to an empty entry.
