NetTcp does not working

[anatoliipp]

Which sample is the bug for https://github.com/CoreWCF/samples/tree/main/Scenarios/Getting-Started-with-CoreWCF/NetCoreServer 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.OnConnectedCoreAsync(FramingConnection connection) at CoreWCF.Channels.Framing.FramingModeHandshakeMiddleware.OnConnectedAsync(FramingConnection connection) at Microsoft.AspNetCore.Server.Kestrel.Core.Internal.Infrastructure.KestrelConnection.ExecuteAsync()

To Reproduce Steps to reproduce the behavior:

1. Run NetCoreServer
2. Run NetCoreClient

Expected behavior I should receive messages in consoles: On the server side: Received Hello World! from client!; On the client site: Hello World!

Repo environment (please complete the following information):

• OS: Windows 10 Pro 21H2
• Architecture x64
• .NET core 3.1
• Rider and Visual Studio

Additional context Add any other context about the problem here.

I'm also seeing the same issue on Windows 11 22H2. Is there a fix or any workaround?

AddServiceEndpoint<EchoService, IEchoService>(new NetTcpBinding(), $"net.tcp://localhost:{NETTCP_PORT}/netTcp") var factory = new ChannelFactory<IEchoService>(binding, new EndpointAddress($"{hostAddr}/EchoService/netTcp"));

I also encountered this issue today. I believe the client's address is incorrect and should be "{hostAddr}/netTcp".
