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

public delegate TResponse BlockingUnaryCallContinuation<TRequest, TResponse>(TRequest request, ClientInterceptorContext<TRequest, TResponse> context)
    where TRequest : class where TResponse : class;

Represents a continuation for intercepting simple blocking invocations. A delegate of this type is passed to the BlockingUnaryCall 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 context and request values as it sees fit.
