C# WebSocket Servers -- Fleck, SuperSocket, TouchSocke

Popularity:198 ℃/2024-09-26 17:16:38

Recently in the maintenance of the old project, the feeling that the memory has been a problem , to locate the problem is a WebSocketServer problem , to understand the Fleck, SuperSocket, TouchSocke and other open-source projects , here to record .

The .net5, .net6, .net7, and .net8 projects have integrated WebSocket with just the () code, for more information seeWebSockets support in Core | Microsoft Learn
