UnreferenceDisposable made slimmer

[Scooletz]

A minor adjustement in UnreferenceDisposable so that it's smaller. UnreferenceDisposable had two references previously. One for the session, one for the time provider. Now it has one so whenever UnreferenceDisposable is created for scoping, the allocated object has one less reference to capture.

Motivation and Context

Going through the project and finding optimization opportunities.

How Has This Been Tested?

Locally, unit tests.

Not sure I understand how this is made smaller? It's adding a property when previously only a field was being used.

UnreferenceDisposable had two references previously. One for the session, one for the time provider. Now it has one so whenever UnreferenceDisposable is created for scoping, the allocated object is smaller by one reference.

When you say references, I presume you mean constructor parameters? While your changes are removing one parameter, they are also introducing a property getter in the containing class, so from an IL size perspective this is probably increasing it rather than decreasing it.

I mean the underlying fields created behind the scenes. Before this PR there are two fields in UnreferenceDisposable that hold references. After this PR there's one field.

I see, thanks.
