[2005] Making a huge app / solution / projects

We are about to embark on developing a huge app - VB for the main UI - asp.net for some sister app's...

I found this white paper on structuring solutions and projects...

http://msdn.microsoft.com/en-us/library/ms998208.aspx

It's going to be VB winform / asp.net web form for front end - a real BL and DL (something I've never done before) - strong 3-tier/OO architecure...

Does anyone have any suggestions or techniques that they like to use.

My only production VS app so far has been for a pocket PC!

btw - dll's in the old VB6 days - do you still build them in VS? are they assemblies now?

dlls are still alive and well. And as for structure, you'll have to break your methods down according to their function. For example, the print function soul be in your BL, because you probably want a number of forms and methods in your UI layer to have access to it. Good luck!

You would need to architect and design the solution. Don't start with solution in mind, but requirements in mind whence you arrive at a architecturally viable solution with least performance issues.
