Global message queue - Githubissues

Add a global message queue that will receive and foward messages from (view)-models to (view)-models.

Example:

LoginViewModel.cs

public class MainViewModel : Sender<T>, ...
{
    public void LoginAction()
    {
        // send message of type T to any other VM
        base.Send(new { User = this.User, Status = Status.LoggedIn });
    }
}

MainViewModel.cs

public class MainViewModel : Receiver<T>, ...
{
    public override void Receive(T message)
    {
        // received message of type T from another VM
    }
}

Receiver can optionally also handle whether the message gets removed from the global message queue or stays untouched.

This is especially useful for multi-view applications, where extra updates are needed upon some action.

Use case:

Application has an all-users window and a create-new-user window.
New user gets created
All-Users window gets updated with the newly created user
