Describe the problem you'd like to have solved

The System.Text.Json namespace provides functionality for serializing to and deserializing from JavaScript Object Notation (JSON). The library design emphasizes high performance and low memory allocation over an extensive feature set.

Describe the ideal solution

Remove Newtonsoft.Json from Auth0.Core.csproj and use System.Text.Json instead.

This is unfortunately not possible at this time as System.Text.Json is not supported on .NET Framework 4.5.2 that we currently support.

We would need to drop support for everything prior to .NET Framework 4.7.2 for that migration to happen so we'd need to consider that for the next major based on current usage statistics for this library.

I'm going to milestone it to the next major so we can consider it then.

How about Utf8Json which is one of the fastest JSON parsers? (or allow developers to select their own?)

I still forced to use Newtonsoft.Json to work if Auth0.ManagementApi. Hope devs will support System.Text.Json

@frederikprijck Could this issue be reopened and possibly added to a milestone now that 4.5.2 is EOL and removed from this library as of #687?

This project supports back to 4.6.2 and the latest System.Test.Json also supports back to 4.6.2.
