Removal of Microsoft.CSharp package dependency

[thompson-tomo]

Describe the solution you'd like
I would like for the Microsoft.CSharp package to be removed as a dependency as it appears to not be used and as such is just bloating the dependencies

Describe alternatives you've considered
Implementing more target frameworks but if not needed for net standard 2.0 we don't gain by adding a framework rather than simply cleaning the package

Additional context
Appears to have been introduced with pull request #7 in 1.3.4

Hey @thompson-tomo,

We'd like to do this but I'm not sure we can right now (easily at least). This is required for older versions of .NET to make dynamic work. At the moment, we only seem to target .net standard, which would still need this I believe.

We probably can and should rework the build in this project to bring it up to date but that's probably a bigger task than just this. So in the short term I'm open to suggestions that don't break this project for folks using older versions of .NET

Hi @sighphyre before i logged this issue, i had taken a look and it for some reason was able to compile without that dependency however when i retested this morning, that wasn't the case. So must of been a cache issue or something. However what i have found is that if we add a netcoreapp 3.1 target this dependency is no longer needed. Hence see PR #204 for additional framework which externalize this dependency. :)
