title: UserControl in same project
body: <p>I have a simple WPF Control project with 1 window and 1 custom user control.  I built the project and the control showed up on the toolbox - great.  I dragged a couple instances of the control onto the window and it worked as expected - great again.  It added an xmlns for 'my' that referenced it's own base namespace and put in the proper references for the controls - perfect.</p>
  
  <p>Then I tried to build it, not so perfect.  It appears that it is looking for it's own build dll so when it starts to build the project and deletes the dll then suddenly it can't find the namespace reference so the build fails.  Then the dll is missing so the designer gives the error.  I can delete the reference to this namespace which fixes the error and I can rebuild successfully, which returns the dll which means I can paste the reference back in with no errors... until I try to build again...</p>
  
  <p>Is there any way to do this without making every control it's own dll?</p>
