I have 2 projects, A and B. in a solutions, both windows applications (ie, outputs .exe's). I want to use windows controls defined in A from B. I add the references of A to B but they don't show up in the toolbox... is this because A is not a DLL/class lib? is there a way around thisbesides creating a 3rd library project? project A is quite complicated and weeding out the parts I need into a control is going to be hard

It would have to be a dll to show up in the toolbox, but you would have to put it there, it would not show up automatically. If the controls are public you can still get to them in code :

A.someControl foo = new A.SomeControl();
