title: Refreshing a stored procedure in entity framework 3.5
body: <p>I am using .NET 3.5 SP1, VS 2008 with the entity framework. I originally added a stored procedure to my model which took 2 parameters. Later, I changed the sproc to just take 1 parameter. I ran the <code>Update Model From Database</code> menu option and confirmed that my sproc was listed in the <code>Refresh</code> tab. Finished up the wizard, cleaned and rebuilt the solution and the model never changed the signature of the sproc. </p>
  
  <p>Why isnt it updating? Is the Update model from database feature broken? Am I missing something? Thanks.</p>
