Answer 1

Are you sure you are no longer referencing these objects? The GC is very good at tuning itself to the needs of your application and would not promote objects to Generation 2 unless you had roots for those objects somewhere.

I think if you figure out where these roots are and ensure that you really are no longer referencing these objects anywhere then the GC will start freeing the memory for those objects and never promote them to Generation 1 let alone Generation 2. Also if you do this then the GC will detect that you need Generation 0 to be larger and will increase the size of the heap on your behalf.
