This type isn't designed to have thread-safety. Even if the id was incremented with Interlocked, the underlying collections aren't thread-safe. And if the collections were made threadsafe then performance would...

What is the benefit of targeting netstandard2.1? As far as I know the netstandard2.0 assembly will work fine. I don't want to add an extra assembly and increase the package...

I don't like making internal methods public that aren't designed to be used publicly. Is there any reason you can't copy of the code from JsonSerializationException.Create and JsonPosition.FormatMessage, and throw...

I'm not sure about this. There are 3 other ASCII separators characters. Why not them as well? Why not semi-colons or fullstops? etc No delimiter makes sense to me, and...
