in Unity 2021.3 or newer, The following error seems to have occurred during installation.

Assembly 'Assets/Plugins/Microsoft.Extensions.Logging.dll' will not be loaded due to errors:
Unable to resolve reference 'System.Diagnostics.DiagnosticSource'. Is the assembly missing or incompatible with the current platform?
Reference validation can be disabled in the Plugin Inspector.

• Simply I added the System.Diagnostics.DiagnosticSource.dll file in the package.
• The minimum supported version is specified in package.json.

Consideration

If the minimum supported version is 2021.3, there is no need to separate the netstandard 2.0 and 2.1 packages.

• Unity2021.3 + .NET Framework dlls : ✅

According to the issue comments, the windows target does not require additional dlls (?) 🤔 🤔 I would like to investigate this further.

I tried to follow up in a Windows environment.

In all environments, System.Diagnostics.DiagnosticsSource.dll was missing.
