Update to .Net 7 and modernize the code where possible

[SpaceOgre]

Starting a new issue for this so we can keep it separate.

Which versions would you like to target, do you want to keep standard 1.0 and 4.6.1?
Otherwise it might be good to drop them and target:

• standard2.0
• net6
• net7

What do you think?

My current strategy is to keep backwards compatibility as much as possible. I don't work in .net stack for a while and may be wrong, but it seems I have no better choice than keeping the old version in LTS and make a new code base for net7. Does it make sense?

I have started to look into it, but Net Framework 4.6.2 is the oldest version still supporten by Microsoft: https://learn.microsoft.com/en-us/lifecycle/products/microsoft-net-framework
And Net Standard 2.0 is compatible with that version.

So Net Standard 1 can be removed I think, and 4.6.1 replaced with 4.6.2.

If someone is stuck on folder versions than this and dont want or can upgrade can use the 1.0.3 version of this package.
