果园signalr CryptographicException

Question

我在2008年windows服务器上的IIS上部署了带有SignalR 1.3.1聊天模块的Orchard异常。它在调试环境中运行良好。

The data protection operation was unsuccessful. This may have been caused by not having the user profile loaded for the current thread's user context, which may be the case when the thread is impersonating.

 Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

 Exception Details: System.Security.Cryptography.CryptographicException: The data protection operation was unsuccessful. This may have been caused by not having the user profile loaded for the current thread's user context, which may be the case when the thread is impersonating.

同样的问题的解决方法被描述为这里，但是我想不出如何将它应用于果园

提前感谢

模块有一个错误。

可以通过将CoreModule.cs添加到Load(ContainerBuilder moduleBuilder)方法行中来修复此问题：

moduleBuilder.RegisterType<MachineKeyProtectedData>()
  .As<IProtectedData>();
