sdk: update to dotnet48

[KevinZonda]

The origin SDK is .NET45, I think it's too old.
New SDK provides more features and makes plugin development much easier. And I think cross SDK version may cause some problems, especially when subproject's SDK is higher than framework which subproject uses.

The frame version can be changed as long as the Nuget package does not report errors.

PS: New framework is develop, use nuget and msbuild will manage install and build. using .Net Framework 4.5-5.0

I mean that subproj(CQ plugin) may be limited by SDK version.

Here is the result of crossing .NET version.

Your can changed all project framework version

[KevinZonda]

Absolutely yes, and that's why I push this PR.

My changed All project, can use net472 and net core library.

[Jie2GG]

Note that "Native.Core" project needs to run within the NET Framework, not Net Core

I found that you have netstandard support, lol.
Anyway, updating the base branch's SDK is needed.

Yes, I'm already building a new framework. The existing framework won't change much without major bugs.
