body: <p>i'm using IronPython and i want to create some windows form, 
  i want to create a windows form with some button, and i want to do this in visual studio with iron python,
  i'm using visual studio 2012 integrated edition,
  each time i create an "ironpython windows form" project, when i want to run it, it says:</p>
  
  <blockquote>
    <p>The project is currently set to use the .NET debugger for IronPython
    debugging but the project is configured to start with a CPython
    interpreter. To fix this change the debugger type in project
    properties->Debug->Launch mode</p>
  </blockquote>
  
  <p>when i change debugger to Standard Python Launcher, it says:</p>
  
  <blockquote>
    <p>ImportError: No module named clr</p>
  </blockquote>
