连接到 Windows 服务中自托管的 SignalR 的问题

Question

我一直在尝试连接到本教程中创建的 Windows 服务：

http://www.asp.net/signalr/overview/deployment/tutorial-signalr-self-host

问题是我可以使用它自己的客户端连接到它。但是，我尝试从控制台应用程序连接到它，但没有成功。此外，如果我在控制台应用程序中托管 SignalR Hub，我可以成功连接到它。

我得到的错误是我的客户端版本与服务器不兼容并且连接被拒绝。

这是我尝试连接的样子：

 IHubProxy _hub;
 string url = @"http://localhost:8080/";
 var connection = new HubConnection(url);
 _hub = connection.CreateHubProxy("MyHub");
 _hub.On("addMessage", x => ShowMessage(x));
 connection.Start().Wait();

更新：

正如 Christophe 所指出的，这个问题与 SignalR Java client only supports exactly 1.3 重复，在我的情况下，通过卸载并重新安装所有 SignalR/Owin 软件包来解决。
