title: LINQ and Stored procedures DBML updating problem
body: <p>I am having serious frustration with DBML files not updating when I alter my stored procedures. </p>
  
  <p>This is what happens. I alter my stored procedure. I then delete the stored procedure from the .DBML file and re-add it. It updates correctly in the .DBML file but the .designer.cs file does not get updated. The only workaround I have found is to delete the stored procedure, then delete the table that the stored procedure returns, add the table then add the stored procedure (all in the .DBML file). And this only sometimes does the trick. </p>
  
  <p>Has anyone else had this problem? Surely there is a more suitable way to update DBML files in Visual Studio 2008?</p>
  
  <p>Thanks in advance</p>
