You need to open up your AssemblyInfo.cs file in your DomainServices project and add this line:

[assembly: InternalsVisibleTo("IdeaBlade.Core.SL, PublicKey=0024000004800000940000000602000000240000525341310004000001000100b3f302890eb528"

Extension Method MakeWeak error : I trying to implement a global...

I trying to implement a global cache repository as TempHire does. So, when registering an event with weak reference I receive an error:

Error Message:

Exception has been thrown by the target of an invocation.

Detail:

Attempt by method 'IdeaBlade.Core.WeakEventHandler`2..ctor(System.EventHandler`1, IdeaBlade.Core.UnregisterCallback`1)' to access method 'DomainServices.Helpers.GlobalCacheRepository`1.OnManagerCreated(System.Object, IdeaBlade.EntityModel.EntityManagerCreatedEventArgs)' failed.

Code:

public GlobalCacheRepository(IEntityManagerProvider entityManagerProvider, IGlobalCache globalCache)

: base(entityManagerProvider)

{

_globalCache = globalCache;

entityManagerProvider.ManagerCreated += new EventHandler(OnManagerCreated)

.MakeWeak(eh => entityManagerProvider.ManagerCreated -= eh);

if (globalCache != null)

DefaultQueryStrategy = QueryStrategy.CacheOnly;

}

What am I doing wrong?

PS: If I don't use MakeWeak it works.
