I found the problem, the AuthenticationContext wasn't set on that EntityManager.
 
I have a new error I can't find though.  When executing this statement

            var query = emInboxPromoCatalog.Member_PromoCatalog
                        .With(QueryStrategy.CacheOnly)
                        .Where(memberIDPredicate)
                        .Execute();
 
I get this error:
Unable to get metadata for LEAF.BusinessObjects.Promotions.Member_PromoCatalog. Make sure it is a valid entity type or POCO type with a KeyAttribute

I don't see a request to the server yet so it looks like it's a client side isse (Silverlight).  Where should I look to try and find what is missing? 
 
Thanks,
Sean

Sean,
 
Is all Member_PromoCatalog's partial classes shared/referenced/present in the client?
 
On a separate note, if you expect a request to the server, you should be running this query async. (This is a Silverlight app, correct?)

PromoCatalog.edmx is in it's own project.  It of course has PromoCatalog.edmx.tt and the generated PromoCatalog.IB.Designer.cs in it.  No other classes.
The silverlight app has a file link to PromoCatalog.IB.Designer.cs so it gets included in the compile.
 
And I didn't know what to expect from the call but you're right, it's not a server call.

Hi Sean,
 
Does the issue only occurs with the Member_PromoCatalog entity? Also, does it only occur when querying CacheOnly? Is this a multi-model solution?
 
Can you provide a small solution reproducing the issue?
 
Regards,
   Silvio.

Yes, only that entity and only CacheOnly.  If I skip the CacheOnly, execute the async server request, it runs and returns 2 rows, and if I execute the CacheOnly after that, it runs, returning the 2 rows cached by the async call.
I'll see if I can make a small solution of it. 
By multi-model do you mean multiple edmx's?  If so then yes, there's 7 edmx models and most have been called before this point.
