https://github.com/CoreWCF/samples/tree/main/Scenarios/Getting-Started-with-CoreWCF/NetCoreClient

Describe the bug
When I tried to use NetTcpBindings I received an error:
On the client side:
There was no endpoint listening at net.tcp://localhost:8089/EchoService/netTcp that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.
On the server side:
Now listening on: http://[::]:8088
Now listening on: https://[::]:8443
Now listening on: http://0.0.0.0:8089
Application started. Press Ctrl+C to shut down.
fail: Microsoft.AspNetCore.Server.Kestrel[0]
Unhandled exception while processing 0HMKKHCH4NHRG.
System.NullReferenceException: Object reference not set to an instance of an object.

at CoreWCF.Channels.Framing.FramingModeHandshakeMiddleware.OnConnectedAsync(FramingConnection connection)

To Reproduce

On the server side:
