wcf: InvalidOperationException: There was an error reflecting 'ticket'.

This is from the WSDL from before but hand corrected to fix errors that the SvcUtil was reporting during proxy creation.

I am now getting an error when trying to use the service, namely the loginAsync method. I get the following errors:

System.AggregateException
  HResult=0x80131500
  Message=One or more errors occurred.
  Source=System.Private.CoreLib
  StackTrace:
   at System.Threading.Tasks.Task`1.GetResultCore(Boolean waitCompletionNotification)
   at Test.Service.UnitTest1.TestMethod2() in C:\Source\Service\Test.Service\UnitTest1.cs:line 57

Inner Exception 1:
InvalidOperationException: There was an error reflecting 'ticket'.

Inner Exception 2:
InvalidOperationException: There was an error reflecting type 'Service.SoapReference.Authentication.AuthenticationTicket'.

Inner Exception 3:
NullReferenceException: Object reference not set to an instance of an object.
