WebSocketExample and WebSocketWithBroadcasts projects were based on the deprecated HttpListener technique and will not be updated or maintained. They are still in the repository (but not in the VS solution) only because the first two articles reference them. |

Repository for code from my blog posts:
2019-Jan-15: A Simple Multi-Client WebSocket Server
2019-Aug-17: How to Close a WebSocket (Correctly)
2019-Aug-18: A Minimal Full-Feature Kestrel WebSocket Server
The KestrelWebSocketServer and WebSocketClient projects have been updated to .NET Core 3.1.x.
The Kestrel article did not clarify how I ran the project and I think this caused problems for some people. I set up Visual Studio to run the project in console mode (not under IIS Express or IIS). I also disabled browser auto-launch, which I think will open localhost to the wrong port. In the code Kestrel is configured for localhost:8080. I simply forgot that these settings aren't saved as part of the project file.
I've just now re-tested both projects and they are working normally under Win10, as well as Raspbian Linux on a Raspberry Pi 4B. 😁
