Stack and heap are memory sections of the .net application. The CLR(Common Language Runtime) is in charge of managing those sections. Value type variables are stored in the stack where storing order is Last in first out. When a variable is out of scope it basically fall off the stack. Reference type variable are stored on the heap where storing order is First in first out. When a variable becomes out of scope it is mark for collection. The GC(Garbage Collector) is the part of the CLR responsible for cleaning up the heap releasing resources occupied by Reference type variables.
