Hi Rocky,

I have this test project I mentioned in another thread . Using mobile proxy/serializer It runs on CSLA .NET 4.5.23-Beta under NET 4.5. There is this ExecutionLocation issue that you are aware.

The same project reports an error on CSLA .NET 4.5.23-Beta under NET 4.0. I tested it on VS2010 and VS 2012 and got the same error. Using the old WcfProxy there is no problem.

The error is the following

System.TypeLoadException was unhandled
  HResult=-2146233054
  Message=Could not load type 'Csla.DataPortalClient.MobileProxy' from assembly 'Csla'.
  Source=Csla

MobileProxy is not available to .NET 4 clients. It uses async features not available to .NET 4 clients.

Correct. Updating BCL packages to the now stable release solves the issue. I also had to replicate Service References content to Csla.Net4 project. BTW the test project is running on VS2010.
