Register classes derived off IViewFor for D-I, when located in 2 assemblies?

[Mark Pawelek]

In the sample WPF ReactiveUI Application <https://reactiveui.net/docs/getting-started/>, one has to "register all classes that derive off IViewFor into our dependency injection container". 

namespace ReactiveDemo

{

    using System;

    using System.Linq;

    using System.Reflection;

    using System.Windows;

    using ReactiveUI;

    using Splat;

    public partial class App : Application

    {

        public App()

        {

            // register all classes that derive off IViewFor into our dependency injection container

            Locator.CurrentMutable.RegisterViewsForViewModels(Assembly.GetCallingAssembly());

        }

    }

}

I'm wrting a mixed WinForms / WPF application. The main program is a Windows.Application, and the WPF windows exist in a class library. (a "WPF Custom Control Library").

I have not been using a D-I container up till now. I'm trying to add ReactiveUI for both WinForms and WPF views; as and when required for new features. So I have classes in 2 assemblies deriving from IViewFor.

Can I still use Splat to do this?  Is there an easy way?
