title: "Type is not defined" error on project build
body: <p>I created a new VB.net windows applications project and added a reference to my utilities project like I have done many times before. When I start coding, the editor will find the utility namespace without difficulty but when I build I get "Type My.Utils.Data is not defined". </p>
  
  <p>I've compared my project to my other projects and can't find a difference. </p>
  
  <p>When I try to debug, I get a dialog saying "Visual Studio cannot start debugging because the debug target "C:.....\myproject.exe" is missing</p>
