Signalr Orchard信号加密异常

我在Orchard上遇到了这个例外，在windows server 2008上已在IIS上卸载。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.

 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.

数据保护操作未成功。这可能是由于没有为当前线程的用户上下文加载用户配置文件造成的，这可能是线程正在模拟的情况。

同样的问题的解决方法也有描述，但我不知道如何将其应用到果园中

提前感谢

模块有一个

您可以通过添加到加载（ContainerBuilder moduleBuilder）方法行中的CoreModule.cs来解决此问题：

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

moduleBuilder.RegisterType（）
.As（）；
