Question

我正在使用SignalR 2.0和MVC5 here的聊天演示。我添加了一个NServiceBus背板，在IISExpress中一切正常。

但是，当我在Windows 7上的IIS 7.5中托管时，我的客户端回调没有触发。我打开了客户端登录，这是日志：

maybe the server is down chat:91

[14:13:52 GMT-0600 (Central Standard Time)] SignalR: Fired ajax abort async = true.

AppPool是为.NET 4.0配置的，我在web.config中有这个：

<modules runAllManagedModulesForAllRequests="true"/>

任何帮助将不胜感激。感谢。

建议不要在客户端操作系统上使用完整版本的IIS。请参阅此处的“支持的服务器IIS版本”：

我不认为这个问题是由于将SignalR与nservicebus和IIS结合使用引起的，我有不同的工作解决方案。您提到的IIS设置与我的解决方案相同。我也在Windows 7上运行IIS也许你可以在web.config中找到不同的东西这是我的：
