Answer 1

I can think of two possible reasons off the top of my head:

1. You're running in debug. References in debug last longer than in release, and possibly longer than you might think.
2. You have a reference to a string, which since it is a constant, is probably interned (ie not dynamically allocated), and will never be collected.
