In general, if you are using the commercial editions of Visual Studio 2008/2010, you should have all the OpenAccess templates in place once OpenAccess ORM is installed.
Can you verify that .NET Framework 4.0 is selected on the Add New Project screen? Also - are the templates the only thing missing or you are experiencing other issues? For instance, can you create a Domain Model and to see your persistent classes in the Visual Designer, when you open the generated RLINQ file?
I am looking forward to your feedback.
