title: Visual Studio break all in debug
body: <p>I have a solution, both client and server running, with many projects, the front end is Silverlight in my solution. 
  As the code is running I hit break all and expect to stop in the currently running line of code. Instead I receive the "No Source Available, There is no source code available for the current location" message.
  What could be the solution for this?
  Note that it happens whenever I hit break all, no matter which part is being executed. standard breakpoints do stop. </p>
