Our development team recently switched from a XP(x86) boxes over to Win 7(64bit) boxes and this is when we noticed the issue.
When running a build on the new Win 7 machines the app loads the shell and everythings ok at that point. When prism tries to download modules is when we recieve the white screen.
With the following error:
Failed to load type for module X.
If this error occurred when using MEF in a Silverlight application, please ensure that the CopyLocal property of the reference to the MefExtensions assembly is set to true in the main application/shell and false in all other assemblies.
Error was: The remote server returned an error: NotFound..
We are not using MEF and have none of the MEF assemblies installed.
We have also tried running the Quick-Start ModularityWithUnity app and have the same issue on the Win7 machines and runs great on the old XP machines....
Has anyone else had an issue like this? Is there a setting in VS that we're missing?
