title: ASP.NET 'CommandType' is not a member of 'Data' all of the sudden
body: <p>I was trying to install some new DLL's on my site and I've created a site wide issue.  I don't really know how to fix this, but I feel like it should be relatively simple.   I think I've deleted a reference or a dll or something.</p>
  
  <p>Everywhere I call a stored procedure I was setting the CommandType with this syntax: <code>CommandType = Data.CommandType.StoredProcedure</code> </p>
  
  <p>This no longer works, it says 'CommandType' is not a member of 'Data'.  If I rewrite each statement like this the page works again: <code>CommandType = CommandType.StoredProcedure</code> </p>
  
  <p>What have I done to my site?  Any insight?</p>
