Hi, thanks for posting!
At the moment NCrunch doesn't officially support Silverlight projects, so I can't guarantee that it will be possible to get this working.
One thing that may work is to add the entire Web project (with all of its source files) to the linking project by using the 'Additional files to include' configuration setting. This will cause NCrunch to copy the Web project adjacent to the linking project as if it were an additional resource. Essentially NCrunch creates separate sandboxed
workspaces for each of your projects, stripping out the relationships between them and managing these relationships dynamically inside the workspaces. Right now NCrunch does not support handling WCF RIA Services links.
Cheers,
Remco
