Garbage collection occurs when one of the following conditions is true:
1. The system has low physical memory.

2. The memory that is used by allocated objects on the managed heap surpasses an acceptable threshold. This threshold is continuously adjusted as the process runs.

3. The GC.Collect method is called. In almost all cases, you do not have to call this method, because the garbage collector runs continuously. This method is primarily used for unique situations and testing.

Garbage” consists of objects created during a program’s execution on the managed heap that are no longer accessible by the program. Their memory can be reclaimed and reused with no averse effects.

Garbage collection is usually triggered when allocating storage for new objects - specifically when generation zero's budget is exhausted. I.e. there may be a significant delay between when objects are illegible for garbage collection and when they are actually collected. As others have already pointed out, the CLR doesn't use reference counting. Instead it employs a mark and sweep approach.

When application runs at the same moment .Net garbage collector starts working as a separate thread. This thread will be running always at the back end.
