Revert changes that make parameters local

[sagi1623]

As it can be seen in this comment, I realised making Parameters local was a mistake, as Named arguments is a thing for both C# and VbNet.
There are actually test cases in the Expressions file for both C# and VbNet, that I have glimpsed over because of the sheer amount of changes the PR introduced.

Sorry once more for the mistake.

@olafurpg,

I have made a mistake in the previous PR! Sorry for that.
This one is here to revert part of the changes I have done there.
I promise, next time I will think twice before doing changes.

LGTM 👍🏻 Thank you so much for following up on this. I should have been more careful with the review, I'm not familiar enough with C# to know at the top of my head that it supports named arguments (although I recall it did, I ignored it in the PR).

[sagi1623]

It is completely my fault for missing the named argument usage.
The problem is that even though I enjoy working on this a lot, I usually don't have the time to do so during the day. And after a full workday around 10 PM in the evening it is easy for me to miss things. I promise I will be more careful in the future.

@sagi1623 no worries at all!
