There was a problem hiding this comment.
I wonder if there's a more concise way of expressing this. My understanding is that if there is an out parameter then all parameters have to be listed complete with types.

Context
Fixing a few places where we allocated objects unnecessarily. This is by no means exhaustive.
Changes Made
GetOrAddshould be given a delegate to a method that creates a new object, not the new object itself. Otherwise we allocate and throw away the object in the "Get" case.Testing
Existing unit tests.
