In the article A Billy Hollis Hybrid Shell (written by the framework coordinator) the author showed a nice way to handle both dialog and message boxes, but he used dependency injection (you can go without DI of course but it makes things simpler). The main idea is that you can let your main window, the one used as the application shell implement an interface that looks something like this:

public interface IDialogManager
    {

        void ShowDialog(IScreen dialogModel);
        void ShowMessageBox(string message, string title = null, MessageBoxOptions options = MessageBoxOptions.Ok, Action callback = null);

    }

and then he registers this interface with the IoC container, I guess you can use your imagination from there on and if you don't have time then you can look at the source code that accompanies the article.
