title: Can't drag stored procedure onto dbml designer
body: <p>I'm trying to do a simple call to a database stored procedure from a C# application.</p>
  
  <p>I'm following a guide like, e.g., <a href="http://msdn.microsoft.com/en-us/library/bb918119.aspx" rel="noreferrer">this one</a> or <a href="http://msdn.microsoft.com/en-us/library/bb384428.aspx" rel="noreferrer">this one.</a></p>
  
  <p>Both of these have the same basic steps.</p>
  
  <ol>
  <li>Add a LINQ to SQL .dbml item to my project</li>
  <li>Connect to a database in Server Explorer</li>
  <li>Drag a stored procedure from the Server Explorer onto my .dbml designer window</li>
  </ol>
  
  <p>But step 3 doesn't work. I have my stored procedure and my designer window, but I can't drag the sproc. I don't get a plus sign, or a "not allowed" sign. It's just a non-dragable object.</p>
  
  <p>I can't find another way to add my sproc to the .dbml file. And I can't find anyone else who has had this problem. Every source simply says to drag it over.</p>
  
  <p>What could I be doing wrong here?</p>
