Request Reply replace REST

[alberk8]

Is a good approach to use request reply to replace REST API for micro services between aspnet app?

You can use the Services API as well https://nats-io.github.io/nats.net.v2/documentation/services/intro.html

edit: Coincidentally Jeremy just released a video on YouTube about micro services which might be useful.

I looks good but when I read the code the first thing I wonder is where does the class MyClass get initialized?

I personally prefer the app.MapNatService<T>() if that is possible, it is so much easier to track down (follow the code).

var registrar = INatsSvcEndpointRegistrar.GetRegistrar();
await registrar.RegisterEndpointsAsync(testService);

The method RegisterEndpointsAsync uses Source Generation to scan the entire project for methods tagged with
[ServiceEndpoint("endpointName", "queueGroup")] and registers them using AddEndpointAsync<T>

I am working on another flavor of this where it mimics the functionality of ControllerBase to work similarly to an API Controller in ASP.NET

Thank you, This going to be awesome. 👍

@adamreed90 , I cloned the repo with your pull request, Running the EndpointRegistrationTest,
The line hitting the error is await registrar.RegisterEndpointsAsync(testService).

Exception thrown: 'System.NullReferenceException' in EndpointRegistrationTest.dll
Object reference not set to an instance of an object.

Not sure why you're getting that error, but this was just a proof of concept, I've started a new approach that I'll be finishing up this weekend most likely. Stay tuned!
