title: MonoTouch: Adding DLL references in sub projects
body: <p>In a way I am looking for best-practice here.</p>
  
  <p>I have a common project that is shared by many of my apps. This project has FlurryAnaylics and the ATMHud DLLs as references.</p>
  
  <p>If I do not also reference these DLLs in the main project, the apps will often, but not always, fail in the debug-to-device test. In the debug-to-simulator I don't need to add these DLLs to the main project.</p>
  
  <p>So, the question is: Do I have to include references to DLLs in the main project that I have in sub projects all the time?</p>
