Use c# 12 primary constructors

Changes:

• Use c# 12 primary constructors

One more discussion point:

I can add editorconfig option in next pr (because maybe you want to merge another PR and I don't want to block them now) for this and VS will warn to use primary constructors if possible.
It will make code style more consistent.
Do we want to have it or we need to have a more flexibility at this area?

Ready to hear you opinions

Thanks @Romfos . I think it's fine to add editorconfig.
