In developing VS C# applications, are you guys compiling all window forms into your EXE or just some (the rest would be external to the EXE)?

How are you managing compiling the external forms to DLL files? Are you using Visual Studio to create the FORM.CS and FORM.DESIGNER.CS -- and then how are you converting them into DLLs? Is there an easy way of doing this? I have 14 3" books (that cost me $750) and I can't find one simple answer (sorry to be venting).

Obviously the second paragraph would have no answer if you compile all windows into your EXE.

Thanks in advance and happy belated New Year to everyone.
