Allow net50 in addition to netstandard 2.0?

[IceReaper]

Does anything specific speak against supporting net50 as target framework?
I am currently using special empty H5 csproj files which point on the same libraries i use in desktop environment.
However defining the projects as net5.0 would not require out libraries to avoid using modern language features like switch expressions etc.

@IceReaper I've to test, but the most probably issue is missing APIs that have to be identified and implemented in the standard library. netstandard2.0 has a smaller subset of APIs than netstandard2.1 and subsequently net5.0
