title: Entity Framework gives me the old data although i changed them
body: <p>I have a strange problem with the Entity Framework:</p>
  
  <p>I have a SQL Server database on a Windows Server and I access it via my app through Entity Framework.</p>
  
  <p>Now I changed an entry in the database, but the app which uses Entity Framework still gives me the old value although its not saved in any place.</p>
  
  <p>What could this be and how to fix this?</p>
  
  <p><strong>EDIT</strong>:<br>
  I'm getting the data from the database like this: </p>
  
  <pre><code>(from p in _myEF.master_Items where p.id == userId 
   select p.Location).FirstOrDefault();
  </code></pre>
  
  <p><strong>EDIT2</strong>:<br>
  when I start it locally via Visual Studio I see the new value. If I use the deployed version, I see the old value which is not in the DB anymore</p>
  
  <p><strong>EDIT3</strong>:
  here is my connection string <code>&lt;add name="MyEntities" connectionString="metadata=res://*/MyData.csdl|res://*/MyData.ssdl|res://*/MyData.msl;provider=System.Data.SqlClient;provider connection string=&amp;quot;data source=foo;initial catalog=MyDb;persist security info=True;user id=Admin;password=xxxx;multipleactiveresultsets=True;App=EntityFramework&amp;quot;" providerName="System.Data.EntityClient" /&gt;</code></p>
