You can read the following 2-part article from MSDN. It quite nicely
explains how .Net garbage collector works -- it's also (partly*) copying &
generational collector at one (it even has 2 generations).

*) it's copying GC for not too large objects (AFAIR less than 16KB), larger
objects are allocated from yet another heap and are unmoveable (as moving
large obiects to compact memory is too slow)
