title: Reference project "readonly" in Visual Studio?
body: <p>I have two applications in two solutions in VS2008 that share a common dll, the dll-code is included as a project in the first applications solution.</p>
  
  <p>Is it possible to allow the second solution to reference the dll project "readonly"?</p>
  
  <p>I want whoever opens the second solution to be able to step into the dll during debugging but not be able to change the code.</p>
