Detailed Description

A simplified version of Replier that can be used to reply to incoming requests on an individual basis.

Template Parameters

TRequest	The type of the requests to be received.
TReply	The type of the replies to be sent.

A SimpleReplier is based on an event handler. Requests are passed to the handler, which returns a reply. The reply is directed only to the Requester that sent the request. SimpleRepliers are useful for simple use cases where a single reply for a request can be generated quickly, for example, looking up a table. When more than one reply for a request can be generated or the processing is complex or needs to happen asynchronously, use a Replier instead.

Use participant.BuildSimpleReplier<TRequest, TReply>() (an extension method defined in DomainParticipantRequestReplyExtensions) to configure and build a SimpleReplier.

For example, to create a SimpleReplier:

var simpleReplier = participant.BuildSimpleReplier<FooRequest, FooReply>()
        .WithServiceName("FooService")
        .WithRequestHandler(request => new FooReply(request)")
        .Create();
