System.Object.GetHashCode()

After reading Ayende’s blog about GetHashCode, I found the following PDF file about the pitfalls of GetHashCode. 

I’ve coded it in a Java class but have yet to apply it anywhere else.

I don’t believe I’ve used any objects as keys in my applications.  I
mainly use value objects.  From a friend, I’ve heard that .NET
automatically prevents collisions by doing chaining (if two objects
have the same hashcode, the values are link-listed off that key)

Hash collision resolved by chaining.
