I know that VS2005 cannot be used to compile projects created by Carbide.vs for VS2003 because the compiler architecture is different. At least that's what Mitts explained (did I understand incorrectly?). Is there a way to instruct VS2005 to use a different compiler (like the one that comes with VS2003 or even CW) and debug with the VS2005 debugger? I don't care if I don't have Carbide.vs installed inside VS2005, I can just create the projects inside VS2003 and update the MMP files myself. Is this possible?
