I just added two more columns to my database via SQL Server Management Studio. Now I'd like to use this in my WPF/C# application. How do I update the \*.cs files in my project? I generated These files by adding a new item --> ADO.NET Entity Data Model --> Code first from database (using entity Framework 6).
For some reason I dont have a "model" or something like that.

Do I have to delete the files and add a new item?

Thank you
