The easiest way to create a clean wineprefix is to just delete ~/.wine; however, that will delete whatever apps you already have installed. If you don't want to do that, use the WINEPREFIX variable to install dotnet20 to a different wineprefix. http://wiki.winehq.org/FAQ#head-faf9617c53607e583f6e6ff70a4ac9522d490faf
