【问题描述】：
我已经制作了一个控制台应用程序，它作为信号 r 的主机并监听端口 8089。当我运行 wpf 应用程序并在 localhost 上运行该主机应用程序时，一切正常。现在我已经在服务器上部署了该控制台应用程序.现在当我尝试连接时，它没有通过 wpf 连接。所以后来我读到它只支持 HTTP 协议，读完之后我做了一个网站，它连接到远程服务器上的服务器，并且连接成功。我的问题是有什么方法可以使用 wpf 连接到该服务器。我想制作一个桌面聊天应用程序，其中所有客户端都将连接到同一服务器以便它可以广播。任何帮助将不胜感激

// Branch the pipeline here for requests that start with "/signalr"
app.Map("/signalr", map =>
{
// Setup the CORS middleware to run before SignalR.
// By default this will allow all origins. You can
// configure the set of origins and/or http verbs by
// providing a cors options with a different policy.
map.UseCors(CorsOptions.AllowAll);
var hubConfiguration = new HubConfiguration
{
// You can enable JSONP by uncommenting line below.
// JSONP requests are insecure but some older browsers (and some
// versions of IE) require JSONP to work cross domain
// EnableJSONP = true
};
// Run the SignalR pipeline. We're not using MapSignalR
// since this branch already runs under the "/signalr"
// path.
hubConfiguration.EnableDetailedErrors = true;
map.RunSignalR(hubConfiguration);
});
