Message Handler

In order to handle a message sent to an endpoint you need to implement either the IMessageHandler<> or the IContextMessageHandler<> interface on a class that is typically called the message handler.

Methods

HandleAsync (IMessageHandler<>)

Task HandleAsync(T message, CancellationToken cancellationToken = default);

The <T> generic argument should be the type of the message class you are interested in. This method will contain the actual implementation code that reacts to the message that is passed in directly as message.

HandleAsync (IContextMessageHandler<>)

Task HandleAsync(IHandlerContext<T> context, CancellationToken cancellationToken = default);

The <T> generic argument should be the type of the message class you are interested in. This method will contain the actual implementation code that reacts to the message that is passed in. The message instance is available via the context.Message property, and the context also provides SendAsync/PublishAsync methods for sending further messages.
