Always "missing a using directive or an assembly reference" after installing DotNetty in VS.

Hello,
I'm trying to use DotNetty in Unity client.

When I installed dependent DotNetty packages from Visual Studio Nuget Package Manager, everything seems fine in VS, and a lot of files were downloaded into Packages folder under the Unity project.

But after compilation, Unity shows a lot of "missing a using directive or an assembly reference" (The type or namespace name 'DotNetty' could not be found).

I'm wondering how I can successfully implement DotNetty libraries. It seems DotNetty requires .Net Standard, and my project is running on .Net Standard 2.0. Or, DotNetty is not ready for Unity client yet?

Thank you so much for reading my question.
