I take it from the word (Pinned) that something still has a handle to this object. Do you know how to find out exactly who the who is? Regards Dewy Hi Davy,

This information is definatly pointing me in the right direction but I am getting what you had at the end of your demo:
0:032> !gcroot -nostacks 07a45abc
DOMAIN(06BF2C98):HANDLE(Pinned):64312f8:Root: 089e4260(System.Object[])->
079e5e38(System.Collections.Generic.List`1[[System.Object, mscorlib]])->
07a4ad64(System.Object[])->
07a45abc(BombDrop.Bomb)

For each of the objects that I have I expect them to be free. I take it from the word (Pinned) that something still has a handle to this object.
Do you know how to find out exactly who the who is?

Regards
Dewy
