"Owin.IAppBuilder"不包含"MapSignalR"的定义 [英] 'Owin.IAppBuilder' does not contain a definition for 'MapSignalR'

问题描述

'Owin.IAppBuilder'不包含'MapSignalR'的定义，并且找不到扩展方法'MapSignalR'接受类型为'Owin.IAppBuilder'的第一个参数(您是否缺少使用指令还是程序集引用?)

'Owin.IAppBuilder' does not contain a definition for 'MapSignalR' and no extension method 'MapSignalR' accepting a first argument of type 'Owin.IAppBuilder' could be found (are you missing a using directive or an assembly reference?)

using Microsoft.Owin;
using Owin;

[assembly: OwinStartup(typeof(SignalRChat.Startup))]
namespace SignalRChat
{
    public class Startup
    {
        public void Configuration(IAppBuilder app)
        {
            // Any connection or hub wire up and configuration should go here
            app.MapSignalR();
        }
    }
}  

任何帮助将不胜感激...
