Can I program in C# on a Mac?

Question

I want to learn C# for Unity and my personal computer is a MacBook Air. Can I program in C# on a Mac?

Answer 1

Note that while everyone mentions Mono and Xamarin, which you should absolutely look into for C# development, Unity works on Mac directly, specifically Mac OSX 10.6+

while both use the C# language, some of the paradigms espoused by Unity are a little different from standard C# development. I personally recommend learning both.

ADDENDUM: Note that MS has recently announced that they'll be moving the standard .NET implementation cross-platform, and are doing so with the help of the Mono team, so while there's currently a confusing dual set of tools, it'll be shifting away from this in the future
