Question

我的项目有问题。

我使用ASP.NET MVC和ASP.NET Identity 2.0进行身份验证，我将SignalR添加到项目中，所以现在我有两个Startup.cs文件：

第一个来自根

中的MVC

[assembly: OwinStartupAttribute(typeof(MCWeb_3SR.Startup))]
namespace MCWeb_3SR
{
    public partial class Startup
    {
        public void Configuration(IAppBuilder app)
        {
            ConfigureAuth(app);

        }
    }
}

AppCode文件夹中的SignalR和

[assembly: OwinStartup(typeof(SignalRChat.Startup))]
namespace SignalRChat
{
    public class Startup
    {
        public void Configuration(IAppBuilder app)
        {

            var heartBeat = GlobalHost.DependencyResolver.Resolve<ITransportHeartbeat>();

            var monitor = new PresenceMonitor(heartBeat);
            monitor.StartMonitoring();


            // Any connection or hub wire up and configuration should go here
            app.MapSignalR();
        }
    }
}

但是我收到以下错误

尝试加载应用时发生以下错误。 - 在汇编中发现的OwinStartup属性＆＃39; MCWeb-3SR＆＃39;引用启动类型＆＃39; MCWeb_3SR.Startup＆＃39;与汇编中的属性冲突＆＃39; App_Code.hszoxs_z＆＃39;引用启动类型＆＃39; SignalRChat.ChatStartup＆＃39;因为他们有相同的友好名称＆＃39;。删除或重命名其中一个属性，或直接引用所需的类型。要禁用OWIN启动发现，请添加appSetting owin：AutomaticAppStartup，其值为＆＃34; false＆＃34;在你的web.config中。要指定OWIN启动程序集，类或方法，请在web.config中添加appSetting owin：AppStartup以及完全限定的启动类或配置方法名称。

我尝试添加

[assembly: OwinStartupAttribute("ProductionConfiguration.st", typeof(MCWeb_3SR.Startup))]

到第一个，页面运行但身份验证不起作用。

我怎样才能让它们一起运行？

Answer 1

将您的signalr启动文件移动到App_Start文件夹并将其重命名为Startup.SignalR.cs。它应具有此内容，请注意Configure方法已重命名为ConfigureSignalR：

namespace MCWeb_3SR
{
  public partial class Startup
  {
    public void ConfigureSignalR(IAppBuilder app) {
      var heartBeat = GlobalHost.DependencyResolver.Resolve<ITransportHeartbeat>(); 

      var monitor = new PresenceMonitor(heartBeat); 
      monitor.StartMonitoring(); 


      // Any connection or hub wire up and configuration should go here 
      app.MapSignalR();
    }
  }
}

现在在项目根目录的Startup.cs文件中，在ConfigureAuth（app）之后立即添加一个ConfigureSignalR（app）调用：

[assembly: OwinStartup(typeof(MCWeb_3SR.Startup))]
namespace MCWeb_3SR
{
  public partial class Startup
  {
    public void Configuration(IAppBuilder app) {
      ConfigureAuth(app);
      ConfigureSignalR(app);
    }
  }
}

只要所有Startup部分类具有相同的命名空间，这都应该有效。

您能将这两组代码放入一个OwinStartup文件中吗？

namespace MCWeb_3SR
{
    public class OwinStartup
    {
        public void Configuration(IAppBuilder app)
        {
            ConfigureAuth(app);

            var heartBeat = GlobalHost.DependencyResolver.Resolve<ITransportHeartbeat>();
            var monitor = new PresenceMonitor(heartBeat);
            monitor.StartMonitoring();

            // Any connection or hub wire up and configuration should go here
            app.MapSignalR();
        }
    }
}
