title: VS2010, SqlCE 4.0 not a data source option (only 3.5)
body: <p>With installed: VS2010, SqlCE 4.0 CTP2; </p>
  
  <p>When adding a datasource, in the "Entity Data Model Wizard" > "New Connection"; There is Sql Server Compact 3.5, but not 4.0. (Same for chosing Dataset). Shouldn't it show 4.0 here, or does it matter at all, will the .sdf files be the same as 3.5/4.0? </p>
