Is it still possible to develop C# software for Ubuntu?

Question

I know that in the 2000s a number of popular pieces of software were written in C# for Linux. To list a few:

1. Begal
2. Banshee
3. F-spot
4. Moonlight
5. Moonshine

There was also a IDE called Monodevelop. Is it still possible to develop C#, GUI software for Linux? Or is the whole idea of Mono dead?

Answer 1

Monodevelop is still actively developed

It's no longer packaged for recent versions of Ubuntu

You will have to setup their own repo

Though less popular than it used to be IMHO for desktops, Mono itself is still actively developed and recently mono on mobile platforms.
