I can see wrong connection to database even I change name in web.config (example: PoliNameDatabase.dbo.MyProcedure) where I have to also change this name of database in entity-framework?

When you create a new ObjectContext or DbContext , there will be a default name for the connection string. The connection string should be the only thing you should alter to get the right database. What usually happen is that, for instance, if you have an assembly for Model and another for your application, you would have to change this connection string twice: In the model assembly, so that it would set the default name right and work properly in the designer, and in your web.config or app.config so the application will get in in runtime.

When you have the ObjectContext object, you can inspect the connection string from the property [your_object_context].ConnectionString . From DbContext , you would get it from [your_db_context].Database.Connection.ConnectionString .

After you have the connection string name. Inspect ConfigurationManager.ConnectionStrings for checking it out.
