Question

我错过了什么吗？我不能让SignalR使用WebAPI。我不知道我是否有一些与绘图有关的特殊内容。当我创建一个空项目时，我得到了这段代码。但是，当我尝试合并SignalR时，这不起作用。

OWIN

using System;
using System.Threading.Tasks;
using Microsoft.Owin;
using Owin;

[assembly: OwinStartup(typeof(WebApplication3.Startup))]

namespace WebApplication3
{
public class Startup
{
    public void Configuration(IAppBuilder app)
    {
        app.MapSignalR();
        // For more information on how to configure your application, visit     http://go.microsoft.com/fwlink/?LinkID=316888
    }
}
}

ChatHub

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using Microsoft.AspNet.SignalR;
using System.Threading.Tasks;

namespace WebApplication3
{
public class ChatHub : Hub
{
    public void Hello()
    {
        Clients.All.hello();
    }
    public void Send(string name, string message)
    {
        // Call the broadcastMessage method to update clients.
        var n = Context.User.Identity.Name;

        Clients.All.broadcastMes(n, message);
        //   Clients.Client.
    }

    public override Task OnConnected()
    {
        return base.OnConnected();
    }
    public override Task OnDisconnected()
    {
        // Add your own code here.
        // For example: in a chat application, mark the user as offline, 
        // delete the association between the current connection id and user name.
        return base.OnDisconnected();
    }
}
}
