There are two different things you are trying to do. One is to create two
virtual directories to the same directory - that is possible and you should
be able to browse localhost/VDA and localhost/VDB without any problem.
The second thing is opening the project in VS. What version of VS are you
using? If you are using VS 2005, you can use the Open Website... in IIS and
open the site or Open Website... from File System.
For earlier versions, just create a new empty solution, say "Add existing
project" and then reference the IIS virtual directory. If you created two
empty solutions in different directories, you can reference the same solution
- but I wouldn't know why you would want to do that.
