I am trying to create an Entity Data Model from a SQL Server database using ADO.net in Visual Studio 2012 and I am facing an error that is about the key (primary and foreign):

The table/view 'database.tablename' does not have a primary key defined. The key has been inferred and the definition was created as a read-only table/view.

Is there anyone to help me for solving this problem?

Thanks.

Why does database.tablename not have a primary key, and why can you not create one for it? – InbetweenWeekends Jul 08 '15 at 12:56
It is a view now, so that I can not create a primary key on a view. But I should use this view for data model. – Seçkin Eşer Jul 08 '15 at 13:08
