Architectural help for specifying which handler to use about mediatr HOT 2 CLOSED

Feels almost like I need to be able to do something like

_mediator.SendAsync(request, "SystemA");

... and being able to 'tag' the implementations of the handler (based on namespace or something) during my container setup

unless of course, there's a better, more concrete and less string based way!

From my understanding it looks like you should take a look at the abstract factory pattern (though I'm keen to see other's approaches to the problem are).

This would turn your request into something a little more like this:

public async Task<AccountInformation> Handle(GetAccountInformationRequest request, ISubSystemAbstractFactory abstractFactory)
{
    var subSystem = abstractFactory.CreateSubSystem(request.AccountReference);

    return await _mediator.SendAsync(subSystem.GetAccountInformationRequestFromSystemRequest(request.AccountReference);
}

This post should give you a better understanding of the pattern - http://blog.ploeh.dk/2012/03/15/ImplementinganAbstractFactory/
