The edmx file is taking a long time to load. It's taken 3.5 minutes. That is one problem.
I open up the edmx file using ADO.NET Entity Model Designer only to get to "Update model from Database" and also Model Browser. Is there a way to get to them without having to open up edmx? I don't need see the database diagram at all. I do however need to see the Model Browser to select an entity to delete from time to time.
