I found that if I enable Silverlight 3 Application Library Caching and create extmap files for System.ComponentModel.Composition.dll and System.ComponentModelComposition.Initialization.dll, I get a MEF error. If I disable application library caching
the app works fine.
Should MEF work with App Library caching?
The app runs fine without application library caching.
Here are some details of the error:
System.ComponentModel.Composition.ChangeRejectedException was unhandled by user code
Message="The composition remains unchanged. The changes were rejected because of the following error(s): The composition produced a single composition error. The root cause is provided below. Review the CompositionException.Errors
