C# WebSocket-Sharp 完全指南：从“小白”到“老司机”的进阶之路摘要： WebSocket-Sharp为C#开发者提供高效的实时双向通信解决方案。本文通过场景化类比（如外卖配送）解析其核心特性，包含全双工通信、心跳检测和SSL支持。详细演示了客户端/服务端代码实现，标注关键事件处理逻辑。针对常见问题（如404错误、消息丢失）提供排查方案，并给出高并发场景下的性能优化技巧（心跳间隔、异步处理）。最后介绍了SSL加密配置和异步编程模型，同步与异步处理的性能数据对比显示异步模式可显著降低CPU占用。适合需要构建实时应用的.NET开发者参考。阅读详情

websocket-sharp 需要配置一行：

ws.SslConfiguration.EnabledSslProtocols = System.Security.Authentication.SslProtocols.Tls12 | System.Security.Authentication.SslProtocols.Tls11 | System.Security.Authentication.SslProtocols.Tls;

在win7下正常工作，windows server 2008却不能工作，报错
