title: Is it possible to reference a VS2005 website project from another project in the same solution?
body: <p>I'd like to add nunit testing to a VS2005 C# ASP.NET website project - so that I can excercise methods in the App_Code directory.
  It's recommended that the tests are added as a seperate assembly so that the testing code does not get delivered with the website - in this lies my question:</p>
  
  <p>When I add a new project into the solution which holds the website and try to add a reference to the website project it does not show up in the projects tab - is it possible to reference a website project from another project (without having to convert the website project into a web application project)?</p>
