title: Conversion from 'uniqueidentifier' to 'int' is not supported on the connected database server
body: <p>I'm about to migrate my database from using old membership to the one included in mvc4, which uses <code>int</code> instead of <code>guid</code>.</p>
  
  <p>When changing the type I get following error:</p>
  
  <blockquote>
    <p><em>Conversion from int to uniqueidentifier is not supported on the connected database server.</em></p>
  </blockquote>
  
  <p>How can I change <code>UserId</code> to <code>int</code> via SQL Server Management Studio?</p>
