VIsual Studio 2010 ultimate crashes when I make a SQL Server 2005 project

Every time I try to create a new SQL Server 2005 server project I get this error. Then after I hit ok Visual Studio 2010 crashes.

Could not load file or assembly 'System.Data.SqlServerCe, Version 3.5.1.0, Culture=neutrail, PublicKeyToke=89845dcd908080cc91' or one of it dependencies. The system 开发者_Python百科 cannot find the file specified

Why can't it load this file?

Perform a repair install of VS2010.

In the end I had to do a restore to solve this problem. Not sure what happened but a restore fixed it.
