title: How can I tell Visual Studio I have code not in App_Code folder?
body: <p>We've been using Visual Studio 2005 Team Suite for a fairly large web project.  Now, we're adding another web app into our current project...it is essentially complete, and we're just adding the entire thing as a folder into our current project.  The project builds, runs...everything is fine...but this new sub-project doesn't have any kind of Intellisense that recognizes the classes we've created for this sub-project.  </p>
  
  <p>I think that this is probably because the code for the project isn't in the App_Code folder, and so Visual Studio doesn't know where to find it.  Does that make sense?  If so, what can I do about it?</p>
