title: which is the difference between Grpc.Core.Channel and Grpc.Net.Client.GrpcChannel?
body: <p>I am doing some tests with Grpc and I realize that there is this two types of channels, but I don't know the difference.</p>
  
  <p>But when I am working with certificates, with Grpc.Net.Client.GrpcChannel I can set the certificates but I get an error that the DNS is not solved. If I use Grpc.Core.Channel, I can call to the service, but I get an error because of the certificates, with the error - HTTP/2 over TLS was not negotiated on an HTTP/2-only endpoint.</p>
  
  <p>Which is the difference between the 2 channels?</p>
  
  <p>Thanks.</p>
