Tim,

Thanks for the additional info. I have been working with C# Winforms for a while now and am still getting used to the interface. I have done some work using .NET Winforms as a presentation and BO layer, and FoxPro COM objects as the data-interaction tier, MS SQL as data repository. Speaking more than one computer language is confusing sometimes :-)

>As Einar mentioned just as the other project to your solution. This keeps the project stored where it was and does not affect your ability to open it in it's own solution as before. I believe you can also add the debugging symbols under Tools | options - debugging so that you can step through that code without adding it to your solution.

>>>You are welcome.
>>>Did you add just the class to the Winform project in the Winform solution, or did you add the class project to the Winform solution?
>>>
>>>A solution is a collection of projects, and a project is a collection of classes (and other files). In VS you can not create a project without it being part of a solution (if you can please let me know how because I can't figure it out).
>>
>>Oh, I see. I just added the class code and now I think it is living in two distinct places. I would actually like to keep them separated if possible, because one is a presentation tier Winforms project and the other is a class project of code-only Business Objects.
>>
>>It would be nice to separate them so I could work on each individually without the distraction of the other. The only issue I see is the drill-down feature of the debugger.

>>Appreciate the feedback,
