title: How do I open a SQL CE4 .sdf database file?
body: <p>I installed Microsoft WebMatrix, which, I believe comes with SQL Server CE4. I've tried opening the SDF file in SQL Management Studio (SQL 2008), but I get the following error message:</p>
  
  <blockquote>
    <p>-------- Microsoft SQL Server Management Studio:
    There is no editor available for
    'C:\efTest\App_Data\SchoolRepository.sdf'.</p>
    
    <p>Make sure the application for the file
    type (.sdf) is installed.</p>
  </blockquote>
  
  <p>How do I view/modify my .sdf database?</p>
  
  <p>I see there is a similar question on StackOverflow (http://stackoverflow.com/questions/4070860/sql-compact-4-0-cant-open-read-sdf-file) but I would really like to use Management Studio if I can, and not another 3rd party tool.</p>
