title: Cannot open .sdf files in SQL Server Management Studio 2008 SP3
body: <p>Has made a .sdf database file in Microsoft Visual Web Developer 2010. When I try to open it in SQL Server Management Studio 2008 Service Pack 3, it displays error message:</p>
  
  <blockquote>
    <p>Cannot connect to C:\Users\Xtreme\Documents\Dishes.sdf.</p>
    
    <p>Incompatible Database Version. If this was a compatible file, run
    repair. For other cases refer to documentation. [ Db version =
    4000000,Requested version = 3505053,File name =
    \?\C:\Users\Xtreme\Documents\Dishes.sdf ] (SQL Server Compact ADO.NET
    Data Provider)</p>
  </blockquote>
  
  <p>What is wrong? There is no problem to work with the .sdf in Microsoft Visual Web Developer 2010.</p>
