I'm assuming you are using CSLA 3.8 or 4.

If you are using SL4, you need to make your PropertyInfo<T> fields public.

If you are using SL3, you probably should make them public - or use the _forceInit trick discussed in the Expert 2008 Business Objects book.

The problem is that the static fields of your business types aren't being initialized early enough - making the PropertyInfo<T> fields public will solve that because CSLA 3.8 and higher has code to fix the issue. The _forceInit trick works in SL3, but apparently the JIT compiler in SL4 optimizes the code away when in release mode, so that's not a good solution anymore.

We are using CSLA 3.6 and Silverlight 4.0. after looking at your response i think we should move to CSLA 3.8 or 4.0 with Silverlight 4.0. We are moving to CSLA 3.8 now.

Thanks.
