具有Mosync移动客户端应用程序的SignalR Server桌面应用程序

Question

Now I am developing server desktop application in c#(visual Studio 2012) using SignalR . 现在，我正在使用SignalR在c＃（visual Studio 2012）中开发服务器桌面应用程序。

Client Application using Mosync Mobile application(Mobile Platform Independent) 使用Mosync Mobile应用程序的客户端应用程序（独立于移动平台）

When server application and client application is on same machine(localhost), communication is successfully created and data feed from server to client is working fine. 当服务器应用程序和客户端应用程序位于同一台计算机（本地主机）上时，通信已成功创建，并且从服务器到客户端的数据馈送正常运行。 But When i put server application in remote server, Mosync client application is not communicate with server. 但是，当我将服务器应用程序放在远程服务器中时，Mosync客户端应用程序无法与服务器通信。 Could any one help me? 有人可以帮我吗？

Assuming your code is ok, which it does at first glance, then it is probably either an IIS or network/infrastructure issue. 乍一看，假设您的代码可以，那么它可能是IIS或网络/基础结构问题。 Have you investigated this possibility ? 您是否调查过这种可能性？

SignalR is supported on IIS 7.0 and 7.5, but support for extensionless URLs must be added. IIS 7.0和7.5支持SignalR，但必须添加对无扩展名URL的支持。 To add support for extensionless URLs, see http://support.microsoft.com/kb/980368 要添加对无扩展名URL的支持，请参阅http://support.microsoft.com/kb/980368
