Object o; //Where does o fit in memory?

It allocates enough memory on the stack for a reference (pointer) to the actual object (what ever it may eventually be)

profoundwhispers wrote:
o = new Object(); //Now what? Instantiated? What's that?!

This allocates memory on the heap for the newly instantiated object.

profoundwhispers wrote:
o = some_fuction_that_returns_a_newly_created_object(); //Now?

the actual newly created object will be on the heap. o itself is still a pointer/reference on the stack to that object.

profoundwhispers wrote:
How about the first o that was allocated? ... What happens to the first instance?

The garbage collector will remove it from the system when it gets around to it, assuming nothing else is referencing it.

profoundwhispers wrote:
What about if I want to destroy this o in memory because I simply don't need it anymore?!

If you don't need it anymore just don't reference it. The garbage collector will free the memory when it gets around to it.

One caveat is objects that have a Dispose() method. These usually have resources that the managed heap in .NET cannot garbage collect efficiently. When you no longer need these objects you should call Dispose(). The garbage collector would eventually Dispose it anyway, but it will take a few attempts at it.
