Question

DOT NET garbage collector can only deals with memory resources or it also handles other resources used by orphaned object?

How CLR deals to free these other resources used by orphaned object.

Answer 1

The .Net GC manages only objects that are put up on managed heap, i.e. managed objects. These managed objects may inturn access unmanaged objects like DB connection or a file handle etc. The developer needs to free these resources by implementing IDisposable or Finalize, depending on your needs.

MSDN states that:

A type must implement Finalize when it
uses unmanaged resources such as file
handles or database connections that
must be released when the managed
object that uses them is reclaimed.
See the IDisposable interface for a
complementary and more controllable
means of disposing resources.
