1. If you need to work online, buy a VPS on Hetzner or OVH with Ubuntu.
2. If you are ready to go with VirtualBox on your local computer or replacing your current OS, installing Ubuntu or its derivatives is not very complicated, and there are lots of guides on the internets, text or video ones.

If you don't mind, I'll warn you that developing for Microsoft .NET platform is a bit fishy using linux machine. If your applications do need Windows Forms or other Windows-specific libraries, it wouldn't be possible. If they aren't, you can try Mono (multiplatform free and open source .NET reimplementation with runtime included). And yet one more thing: I don't know any way to run ASP.NET MVP or other web-based .NET applications which are meant to be run with IIS. Think twice.

> is it important to use it with Linux OS?

Yes. Main Linux administration tool is Shell language at command line interface (CLI). Because of it you need good terminal emulator. And there are plenty of them for Linux.

As of my last experience there was no perfect implementation of terminal emulator for Win. All of Win implementations are not so good as native ones for Linux or Mac.

- Command line interface is great when you know what is available.
- Graphics UI is great when you do not know with what you are working.

In order to be a good eng. you need to know well a system you are working with. Because of it there is no way not to end up with usage of terminal as the OS intended to be managed at CLI with scripting language known as Shell. Or you are not a good engineer at finish.
