I'm not primarily a .NET guy (I have done a fair bit though), but why wouldn't it be possible or reasonable to spin up a VPS instance of Windows if it's a platform you're totally familiar with (much like someone being familiar with a linux instance?)

Firing up a linux instance does require more sysadmin skills from the command line (this can be non programmer skills to some), compared to a gui based OS.

Disclaimer: I use linux myself but have spent enough years in the professional world to know that there are things that windows can do equally well, just don't ask it to do everything. A basic startup stack of IIS (included), mysql, and a framework (download asp.net MVC) doesn't take much setup.
