Here's the link of my Model Project
uploads/1228/For_Devforce_Checking.rar - uploads/1228/For_Devforce_Checking.rar

After having hard time making this work with some unusual error such as "Key 'iRelyReportsEntities_Example' object reference.....' when performing query, we eliminate the error by just doing the relationship via Fluent API.

Now, the problem is, when trying a query "Object Ref is still showing but without the Key part"
I noticed that the problem occurs in the client side unlike the first one w/c occurs in the server side..

Here's the stack trace of the error:

I just wonder why it's so complicated using the Devforce Code First over to Database First?
It's just frustrating to have these errors that we didn't experience before we're on Database First.
Not to mention that there are no "user friendly message" when an error occurs.
I hope this can be improved.

Thanks,
Von

Hi Von,
 
The iRely.Reports.Model assembly needs to be "enhanced" by PostSharp.  I see that the iRely.BaseModel assembly contains PostSharp enhancements, but the other assembly does not.  I know that the iRely.Reports.Model project does reference the PostSharp assembly and I don't see any settings which indicate PostSharp processing was skipped, but the assembly definitely does not contain the necessary PostSharp changes.   Rebuild the project, and check the build output window for diagnostics.
 
We agree that the errors you'll find with Code First development are often quite inscrutable, and we're trying to fix that.
