title: Source file not refreshing
body: <p>I am trying to create a Visual Studio  2008 add in, so I have created a Visual Studio Add in Project, pressed F5 to see it run an the icon for my new add in appears at the top of the Tools menu.</p>
  
  <p>So after stopping the execution I made a few changes to the source code and pressed F5 again, no changes what so ever and no debugging because "No symbols have been loaded for this document"</p>
  
  <p>It seams that visual studio is using the first dll that was created. How can I overcome this problem? </p>
