title: Now that VS2015 is out, what's a supported way to modify Roslyn, with debugging support?
body: <p><strong>The Context</strong> </p>
  
  <p>We'd like to modify Roslyn and be able to debug it while compiling with it. Pre-VS2015 release, doing this was a painful process that didn't flow very well.</p>
  
  <p>Our goal is to develop a C# variant compiler. </p>
  
  <p><strong>The Dream</strong></p>
  
  <p>Pre-VS2015, executing and debugging your modded Roslyn required the opening of a second VS IDE (experimental) set to use your modded Roslyn. This process wasn't straight forward to setup properly, and oftentimes would break your VS2015 installation. </p>
  
  <p>Post-VS2015, is there a better setup and process possible to modify and debug Roslyn?</p>
  
  <p>I have installed Visual Studio 2015 but it looks like I need more required bits. After that I'm unsure how to run the tests and try the changes in VS2015.</p>
