Add a framework to embrace MediatR

[Kaliumhexacyanoferrat]

As a developer of a web application, I would like to simply re-use my MediatR handlers and forget about that complicated HTTP stuff, so that I can omit a lot of boilerplate code.

Example

public record GetUserQuery(int Id) : IRequest<User>;

var users = MediatRService.Create()
                          .Get<GetUserDetailsQuery>(":Id"); // automatically calls _mediator.Send(query)

var api = Layout.Create()
                .Add("users", users)
                .AddOpenApi();

Acceptance criteria

• The feature is implemented as new framework
• There is a new template project for this kind of projects
• The feature is documented on the GenHTTP website
• The feature is covered by acceptance tests

Is this using the existing MediatR or create a framework for that?

[Kaliumhexacyanoferrat]

Existing MediatR - interesting part would be to find a clever mapping from queries to HTTP that works with the reflection module / the operation model.

So the idea is to have a REPR pattern option? Because it is already possible to use MediatR normally as in ASP.NET
