Based on https://github.com/grpc/grpc-dotnet/tree/master/examples/Certifier with added .NET Framework 4.8 client.
Client .NET 5.0 works.
Client .NET Framework 4.8 does not work.
You need to:
- Install \grpc_certifier_example\Client\Certs\client.pfx to a "Local Machine\Trusted Root..." on the Server. Cert pass: 1111
