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:

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.
