A property value compatibility check can be triggered as an object graph is materialized during a query.  The property it's complaining about could be on Closing, UserClosing, or even another type accessed via a navigation property on one of these types.  The likely trigger is logic in an entity constructor - so check these; and also if you've overridden any UpdateNullEntity methods in your entities. 
 
If neither of the above looks like the culprit, please send us your EDMX.

I have tried the following 2 queries and get the same error:

   var query = from c in Context.Closings
                        where c.UserClosings.FirstOrDefault().UserId == CurrentUser.Id
                        select c;
            
            query.ExecuteAsync(op => op.Results.ForEach(Closings.Add));

            var query2 = from uc in Context.UserClosings
                         where uc.UserId == CurrentUser.Id
                         select uc;
            query2 = query2.Include("Closing");
            var op2 = query2.ExecuteAsync();


--------

The error I get is:

Value is not compatible with property: Id DataType: System.Int32


I have checked my model and my data and they both look good. Any other ideas?
