title: debug a project with references in Visual studio
body: <p>I have two separete c# projects. One is a helper library that is included as a reference to another main project. The main project solution only has a reference to the helper library and not the entire source code there. I want to run the main project but also want to be able to debug and step through the code in the helper code. How can I do that? I have the source code for both projects.</p>
