title: Visual Studio error when trying to find my database
body: <p>I am a student learning asp.net and I ran into a problem when trying to reconfigure data sources I created.  When I run my web application I am able to edit/add/delete entries that are in my database but when I try to create or reconfigure a datasource it gives me this message:</p>
  
  <blockquote>
    <p>Database schema could not be retrieved for this connection. Please 
    make sure the connection settings are correct and that the database is
    online.</p>
    
    <p>Could not load file or assembly 
    ‘Microsoft.SqlServer.Management.Sdk.Sfc, Version=10.0.0.0, Culture=
    neutral, PublicKey Token=89845dcd8080cc91’ or one of its 
    dependencies. The system cannot find the file specified.</p>
  </blockquote>
  
  <p>Now I never changed the place of the database on my computer and I have never deleted it from the originating folder. I went into my 'Sever Explorer' tab and it shows that the database is connected. I right clicked on my database in the data connections list and went to 'Modify Connection...' and ran the 'Test Connection' option and it says the "Test connection succeeded". If my application can edit the database why can't Microsoft Visual Studio find the connection to let me edit the datasource?  </p>
