How to decouple MediatR from my business layer

Question

Good morning.

I'm using domain events in my project, and the easiest way i found to implement it was by using MediatR. But i don't want my project to directly depend on it, i want apply dependency inversion to hide the library.

Current code that has a dependency in Mediator, because of INotification interface

public class EmailConfirmedEvent : INotification
{
    public Guid PassengerId { get; }
    public string Email { get; }

    public EmailConfirmedEvent(Guid passengerId, string email)
    {
        Email = email;
        PassengerId = passengerId;
    }
}

But i want to be like this:

public class EmailConfirmedEvent : IMyProjectDomainEvent
{
    public Guid PassengerId { get; }
    public string Email { get; }

    public EmailConfirmedEvent(Guid passengerId, string email)
    {
        Email = email;
        PassengerId = passengerId;
    }
}

By some way i'll need to "convert" from mediator events/event handlers to my project events/event handlers.

What's the best way to do this. Thanks in advance.

I ended up creating my domain event custom code using StructureMap and reflection to resolve the event handlers at runtime. Code sample here: https://github.com/Henry-Keys/domain-events-sample
