Test C♯ code online with repl.it
I've known about repl.it for a while now. It is a site that provides you with a REPL (Read-Eval-Print-Loop) for many different languages, without you having to install the language in question thanks to the native client.
A REPL (in case you didn't know) is like a command prompt, but for a specific programming language or environment. For example, if you type node into your command prompt (if you have Node.js installed), it will start a REPL for you to play around with.
Recently I have discovered that repl.it also supports C♯ (via the mono compiler version 4.0.4.0 at the time of typing), and it lets you write, compile and run C♯ code without ever leaving your browser. I was so surprised by this I thought that I'd make a blog post about it. Apparently you can even embed things you've created into other pages too - here's a small test program I wrote whilst playing around with it:

Update: Corrected The expansion of REPL.
