title: Can't Add LINQ to SQL classes to projects in VS2010
body: <p>I just ran into something in Visual Studio 2010 RC that wasn't previously happening (like, yesterday).  No software changes here, but I did run into some muck yesterday when compiling that required a reboot.</p>
  
  <p>I am unable to add LINQ to SQL classes to any project through the add dialog. I have created ASP.NET web sites, ASP.NET MVC projects - both of these as 'templated' and as 'empty' - and there appear to be no templates installed or available.</p>

  <p>I have made sure that the project targets the 4.0 Framework.  I can easily add a new database and the ADO.NET entity framework templates are there.</p>
  
  <p>As a workaround I can copy a DBML file to my project, delete all tables and sprocs, update the connection string and use the leftover shell (the designer works fine like this), but it's a pain.</p>
  
  <p>Has anyone else had their templates drop?  Figured out how to reinstall them?</p>
