我正在尝试创建一个服务来将交换通知推送到 asp.net 应用程序，最终使用 SignalR。
我的计划是创建一个通知中心，在每个用户登录到 asp 应用程序时订阅他们并为他们收听通知。收到通知后，项目的第二部分是使用 signalR 仅向每个用户发送正确的通知。一旦他们注销或超时，通知中心将取消订阅他们。
到目前为止，我已经完成了一些基本测试，并且可以在一个小控制台应用程序中为自己接收带有硬编码凭据的通知。我正在努力解决的是如何同时为多个人执行此操作。例如，我是否必须为每个用户创建单独的线程，还是有更好的方法？
我想无论我将不得不使用模拟而不是持有每个用户的凭据，对吗？如果每个用户有活动会话，我还必须想出一种方法来自动刷新每个用户的超时时间。
下面是我发现并一直在使用的一个小代码，如果任何人都可以分享我如何最好地实现这一目标的任何想法或示例，我将不胜感激。
非常感谢
安迪
