If you add 5.0.0 package or higher to your netstandard 2.0 project you will get following compilation errors as netstandard 2.0 does not "support" pattern matchinge:

netstandard 2.0 does not "support" pattern matching:

It is not the .NET Standard, but rather your language version is C# 7.3. I am using the last language version for the code and consequently for the source packages (C# 10.0 at the moment). The solution is to update version on your side, or to not use the source version, or fork and change the code to the lower version.
