c# - Is the garbage collector in .net system-wide or application-wide?

Question

During discussion with my collegue, I got a doubt that the garbage collector in .net works system wide or application wide.

Means if every application having its own GC then will it effect system performance?

I am little bit confused about that.

Answer 1

Each process has its own managed heap, which will be collected separately.

There's no system-wide heap, so there can be no system-wide GC.

(If you're running multiple CLRs in the same process, they'd each have their own GC too. That's a pretty rare situation though.)
