Delegate Interceptor.AsyncDuplexStreamingCallContinuation<TRequest, TResponse> (2.48.0) 

public delegate AsyncDuplexStreamingCall<TRequest, TResponse> AsyncDuplexStreamingCallContinuation<TRequest, TResponse>(ClientInterceptorContext<TRequest, TResponse> context)
    where TRequest : class where TResponse : class;

Represents a continuation for intercepting asynchronous duplex invocations. A delegate of this type is passed to the AsyncDuplexStreamingCall method when an outgoing invocation is being intercepted and calling the delegate will invoke the next interceptor in the chain, or the underlying call invoker if called from the last interceptor. The interceptor is allowed to call it zero, one, or multiple times, passing it the appropriate request value and context as it sees fit.
