I create a new .edmx and the wizard allows me to choose the tables I want to expose after I pick my connection. I pick one table, and nothing shows on the design surface. The model explorer opens but nothing seems to have happened. Any ideas what's going here? There is a message on the design surface that says use the toolbox. I can drag i开发者_Go百科tems on but I don't seem to be getting the experience I've had in the past with LinqToSql. Am I doing something wrong? In SSMS, I seem to have all the rights I need using Windows Auth. Any ideas what I can try to correct this? happy Friday and thanks for any tips.

Check your Error List window for messages.

One common problem is if the table doesn't have a primary key.
