在IIS Express中测试SignalR应用程序

Question

大家好,我正在使用Visual Studio 2012,并开发了一个简单的应用程序,仅用于审查目的

但是我被困了,因为当我尝试预览应用程序时,我收到以下错误消息

[PlatformNotSupportedException: This operation requires IIS integrated pipeline mode.]
   System.Web.HttpResponse.get_Headers() +9681446
   System.Web.HttpResponseWrapper.get_Headers() +9
   Microsoft.Owin.Host.SystemWeb.OwinCallContext.CreateEnvironment() +309
   Microsoft.Owin.Host.SystemWeb.IntegratedPipeline.IntegratedPipelineContext.GetInitialEnvironment(HttpApplication application) +246
   Microsoft.Owin.Host.SystemWeb.IntegratedPipeline.IntegratedPipelineContext.PrepareInitialContext(HttpApplication application) +15
   Microsoft.Owin.Host.SystemWeb.IntegratedPipeline.IntegratedPipelineContextStage.BeginEvent(Object sender, EventArgs e, AsyncCallback cb, Object extradata) +288
   System.Web.AsyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +285
   System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +155

关于如何解决这个问题的任何想法
