I use Ubuntu as my primary OS but I still do a lot of C# development. So I installed my copy of 7 as a virtual machine using VirtualBox. VirtualBox has seamless mode, with essentially hides the desktop so all the Guest windows can be used side-to-side with the all the Host windows. It's really nice as it almost feels like I have Visual Studio installed on my Host.

Of course it'll be slow on a low-end/old computer because you're essentially running two operating systems at the same time.
