title: Identity change GUID to int
body: <p>How does one change the PK column of the <code>AspNetUser</code> table from a <code>guid</code> to <code>int</code> data type?
  This should now be possible with the latest <code>asp.net-identity</code> version which got released today.</p>
  
  <p>But I can't find anywhere how this is done?</p>
