Laixer.EventBus 1.0.0

Define an event to fire:

interface IUpdateUserProfileEvent : IEvent
{
    User User { get; set; }
}

Then define an handler for the event:

class UpdateUserProfileHandler : IEventHandler<IUpdateUserProfileEvent>
{
    public Task HandleEventAsync(EventHandlerContext<IUpdateUserProfileEvent> context, CancellationToken cancellationToken = default)
    {
        // Handle event

        return Task.Completed;
    }
}

Register the event with the service collection:

public void ConfigureServices(IServiceCollection services)
{    
    services.AddEventBus()
        .AddHandler<IUpdateUserProfileEvent, UpdateUserProfileHandler>(nameof(UpdateUserProfileHandler));
}

Use the event bus to trigger the event:

public class UserOperation
{
    private readonly EventBusService _eventBus;

    public UserController(EventBusService eventBus)
    {
        _eventBus = eventBus;
    }

    public async Task Method(User user)
    {
        // Fire event for updated user profile
        await _eventBus.FireEventAsync(new UpdateUserProfileEvent
        {
            User = user
        });
    }
}
