Error: SignalRRouteExtension.Mapconnection is obsolete. use MapSignalR in Owin Startup class

Question

我正在使用 ASP.NET SignalR 开发 ASP.NET MVC 应用程序。但是我遇到了错误，找不到解决方法。这是我的 global.asax class，当我开始这个项目时，我在这里遇到错误：

 public class MvcApplication : System.Web.HttpApplication
{
    protected void Application_Start(object sender, EventArgs e)
    {
        AreaRegistration.RegisterAllAreas();

        WebApiConfig.Register(GlobalConfiguration.Configuration);
        FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
        RouteConfig.RegisterRoutes(RouteTable.Routes);

        //This is what I added and this is where i am getting the error.
        RouteTable.Routes.MapConnection<NfcConnection>("echo", "/echo");
    }
}

还有我的连接 class 喜欢在底部

public class NfcConnection : PersistentConnection
{
    protected override Task OnConnected(IRequest request, string connectionId)
    {
        string msg = string.Format(
            "A new user {0} has just joined. (ID: {1})",
            request.QueryString["name"], connectionId);
        return Connection.Broadcast(msg);
    }

    protected override Task OnReceived(IRequest request, string connectionId, string data)
    {

        string msg = string.Format(
            "{0}: {1}", request.QueryString["name"], data);
        return Connection.Broadcast(msg);
    }
}

这是广播来自客户端的数据的部分。我的 owin 创业公司 class 也是这样；

 public class Startup
{
    public void Configuration(IAppBuilder app)
    {
        app.MapSignalR();
    }

}

当我开始项目时这一行

RouteTable.Routes.MapConnection<NfcConnection>("echo", "/echo");

给我这个错误；

Error'System.Web.Routing.SignalRRouteExtensions.MapConnection<T>(System.Web.Routing.RouteCollection, string, string)' is obsolete: 'Use IAppBuilder.MapSignalR<TConnection> in an Owin Startup class.

我该如何解决这个问题？

Answer 1

删除：

RouteTable.Routes.MapConnection<NfcConnection>("echo", "/echo");

并更改：

app.MapSignalR();

至：

app.MapSignalR<NfcConnection>("/echo");
