I\'m having a lot of issues with the templates of Visual Studio 2010 SP1 & ADO.NET Entity Framework 4.1
I noticed that other people had these problems, and asked
When you install Visual Studio there is separate component called Microsoft Visual Studio 2010 ADO.NET Entity Framework Tools. You can check that this component is installed in your computer simply by checking installed programs. If the component is not installed you must probably install it again from VS intallation media.
You mentioned that you have a Professional version but still I would expect that your Add New Item will contain much more features - I don't see groups for Windows Forms, WPF and Workflow - all valid groups. It looks like your installation is somehow incomplete or you are using some project template that perhaps don't offer all groups.
Installing EF 4.1 will not add necessary parts from EF 4 which are part of VS installation. EF 4.1 has these features as prerequisity.
