Ends a pending asynchronous client authentication operation started with a previous call to BeginAuthenticateAsClient.
Assembly: System (in System.dll)
asyncResult is null.
asyncResult was not created by a call to BeginAuthenticateAsClient.
The authentication failed and left this object in an unusable state.
There is no pending client authentication to complete.
If the operation has not completed, this method blocks until it does. When the authentication succeeds, you must check the IsEncrypted and IsSigned properties to determine what security services are used by the SslStream. Check the IsMutuallyAuthenticated property to determine whether mutual authentication occurred.
If the authentication fails, you receive a AuthenticationException, and this SslStream is no longer useable. You should close this object and remove all references to it so that it can be collected by the garbage collector.
To perform this operation synchronously, use one of the AuthenticateAsClient method.
