I had been thinking it might be excellent to possess a similar atmosphere to have the ability to possess a couple of class files along with a console program to have the ability to demonstrate core fundamental C#/.Internet programming techniques - live.

Can there be this kind of online live C#/.Internet atmosphere already that people can use to publish on StackOverflow? (Otherwise, I'll publish on Meta).

I discovered that one: Compilr

Allows you compile although not run - still pretty interesting.
