Hey -- i wondered about this one for awhile after downloading one solution after another (from codeproject et al) with multiple projects.

then i found it.

open your solution.
File > Add Project > New Project (or Existing Project)

heh ... it was there the whole time.  No more need for my laptop to have 3-5+ visual studio's open! ... *eyes the taskbar* ... yet i have 3 of them open now.  oh well :P

Yes, Iknow this. But how can you refer to WindowsProject2 from WindowsProject1?
AlexFMCommented:
It is impossible. Referenced project must be class library and not Windows application. Windows doesn't allow dynamic linking between two executable files.

If you have some classes in WindowsProject2 which you want to make available from WindowsProject1, create new Class Library project, move these classes to it and add reference to this library to both Windows projects.

Right.  So if you have a main project and abunchof Controls or something that compile down to libraries ... you can add those projects and add references to their dll's from your main project.

Or, alternatively, if you have abunchof projects ... a client project, a server project (both compile to windows applications), and abunchof libraries ... you can work with them all within the same solution and built them / add references to one another ... if you want something to start when you hit F5, goto the solution's properties and > Single Startup Project ... and select the project you want to run.

Will public variables in one project be seen by other projects in the same solution?
doobdaveCommented:
No, you need an instance of the class to access it's variable (unless they are 'Shared'), but in any case, you will first need a reference to the project, which, as has already been mentioned can only be to a .dll file.
