Description

According to the #50665 I have made a small change. With this change, this method will not use null coalescing operators to fire the ArgumentNullException exception.

It will use ArgumentNullException.ThrowIfNull instead of it.

This is similar to #50666

I also asked for these kinds of pull requests.(#51731)

So, I think this will be acceptable even if only one change has been made.

Thanks for your PR, @aligoren. Someone from the team will get assigned to your PR shortly and we'll get it reviewed.

Thanks
Looks good so long as @BrennanConroy has no perf concern

Thanks @aligoren if you are interested in continuing, I suggest doing in chunks of a single assembly and a single type of change. (Eg ThrowIfNull vs other throw helper methods). That should strike a balance between too small to be efficient and too large to review easily.

Hi @danmoseley. It looks like you just commented on a closed PR. The team will most probably miss it. If you'd like to bring something important up to their attention, consider filing a new issue and add enough details to build context.
