Fixes #100983
When disposing of
HashProviderCng
, this would null out the_hHash
handle. We have asserts elsewhere saying that the handle cannot be null. This may not be true during concurrent (mis-)use.Instead of disposing and nulling it out, just dispose of it. The p/invoke will throw an
ObjectDisposedException
when marshaling the disposed handle which is the desired behavior.
