推荐答案

SignalR连接（包括潜在客户端的所有集线器操作的连接）不支持会话状态。你可以启用它，如果你想，但我们强烈建议反对的会话状态序列化的访问对于给定的客户端请求，这意味着你不会真正得到SignalR双工通信好处了，因为一个请求会阻塞其它如在长轮询传输，接收的连接将阻止任何企图发送。

SignalR connections (including the connection underlying all Hub operations for a client) do not support Session state. You could enable it if you wanted to but we'd strongly recommend against it as session state access serializes requests for a given client, meaning you won't really get the benefit from SignalR duplex messaging anymore, as one request will block the other e.g. in the long polling transport, the receiving connection will block any attempt to send.
