SignalR不會與IIS快遞在Windows 8中使用的Chrome或IE

Question

我剛開始接觸SignalR VS2013所以請原諒我，如果我忽略了一些基本的超建立連接。我的目標是爲用戶提供一個「持有頁面」，直到發生特定事件，服務器端告訴該頁面讓用戶進入流程的下一個步驟。我在服務器上創建了一個Hub，當客戶端調用服務器上的調用時，該Hub似乎正常工作。

問題是客戶端永遠不會從服務器接收任何呼叫和從它出現在客戶端永遠不會建立到轂必要的連接的瀏覽器控制檯輸出。

我在最新的谷歌Chrome和微軟IE瀏覽器V11嘗試這個。我收到了每個瀏覽器中記錄的相同消息。

下面是微軟IE瀏覽器輸出的瀏覽器控制檯（我無法找到一個簡單的方法來保存Chrome的控制檯輸出文本）：

我通過閱讀Introduction to SignalR並知道它將嘗試從最優選的通信技術故障轉移到最不優選的通信技術。從我可以告訴它正在嘗試所有4種方法進行溝通和失敗，最終放棄「停止連接」。信息。

我使用VS 2013和IIS Express的發展，SignalR V2.1.0和ASP.NET MVC 5

更新，包括客戶端代碼

下面是在客戶端腳本用於連接到輪轂：

<!--Reference the SignalR library. --> 
<script src="~/Scripts/jquery.signalR-2.1.0.min.js" type="text/javascript"></script> 
<!--Reference the autogenerated SignalR hub script. --> 
<script src="~/signalr/hubs"></script> 

<script> 
    $.connection.hub.logging = true; 

    $(function() { 
     // Reference the auto-generated proxy for the hub. 
     var chat = $.connection.signingHub; 

     // Create a function that the hub can call back to redirect the user 
     chat.client.signDocument = function() { 
      // Add the message to the page. 
      window.location.assign("/Signing/Initiate/" + ContractID.value + "?clientUserId=" + ClientUserId.value); 
     }; 

     // Start the connection. 
     $.connection.hub.start(); 
    }); 
</script> 

的詳細信息...

我發現這可能是由我從DevExpress使用的第三方組件套件引起的。我可以跟隨聊天示例here和SignalR工作良好。只要我從DevExpress添加MVC擴展控件，SignalR連接協商就會失敗。我在他們的支持論壇here上評論過一個問題，希望能得到答案。

感謝您的幫助，您可以提供！

從DevExpress的支持團隊得到了一些反饋後，看來問題是SignalR 2.1.0的最新版本。我將我的項目降級到v2.0.3，並開始正常工作。你可以看到我與DevExpress支持團隊的對話here。
