    The widely used MediatR library[0] could be used to do that as well, just FYI.

    I gave it a go and I was impressed how easy and fast it was to set it all up. Since I'm not a big fan of REPR pattern almost all my projects are using CQRS pattern with a help of MediatR ]( I immediately started going over something similar that Fast Endpoints offer which is a command bus.
  • MVVM Question: How do you manage the interaction between Model and ViewModel?
    4 projects | /r/csharp | 3 Apr 2023
    I'd use a dedicated event bus based on Reactive Extensions or MediatR to publish domain events from your domain services. This probably doesn't solve all your ViewModel update problems as is, maybe you need to revise the granularity (maybe you can have smaller ViewModels that refresh single property that exposes the Model) and lifespan (sometimes you can create a ViewModel, make it perform it's task and then discard it completely) of your ViewModels.

    Typically if you want to notify interested parties (ViewModels in case of WPF) of Model changes you'd use some kind of pub-sub mechanism like Reactive Extensions or MediatR. Your ViewModel can subscribe to an event bus of some kind (either standalone or maybe exposed by an Aggregate if you follow DDD), your domain logic (which should be located in Model layer, not in ViewModel layer: Service, Repository, DDD Aggregate or whatever you'd like to call it) will then do something useful with your Model and publish the corresponding event to the event bus.
  • Async Methods after setting a property.
    2 projects | /r/csharp | 16 Mar 2023
    If you're finding yourself in a situation where you need to turn this behavior into a pattern because there are a lot of View Models that need to execute async business logic in response to some changes, I'd go with something like MediatR or Reactive Extensions. The idea is, again, that some other, probably business-level, component listens to changes in a decoupled way (that means it doesn't subscribe directly to your View Model, but to an event bus instead). View Model publishes change events to the event bus, and business-component reacts to these events by executing the business logic.
  • I don't get why I should use Redux

    What people really want is to design the logic of an app independently from the component hierarchy. That means you need to store state somewhere other than the components and you need to dispatch events that are not attached to the component hierarchy. Also, a one way data flow has well known benefits as described by things like CQRS, RabbitMQ, and MediatR.
