We have been developing a Silverlight application in Visual Studio 2010. For the last 2 years it has been building with no insurmountable problems. However, for the last two weeks, it has been failing with the following compilation error:
Error 6 The "CreateRiaClientFilesTask" task failed unexpectedly.

Looking on the Web, lots of people seem to have had this issue of the CreateRiaClientFilesTask failing and many and varied fixes have been suggested, none of which so far have worked for me. If you have any suggestions, they would be gratefully received.
