Clarification for any one searching this with regards to Inherited Class

Ex :

    public static IEnumerable GetTypesInherit(this Assembly assembly)
    {
        var types = assembly.GetTypes()
            .Where(myType => myType.IsClass && !myType.IsAbstract && myType.IsSubclassOf(typeof(T)))
            .ToList();

        return types;
    }

Installer :

    public static IContainer Install()
    {
        var builder = new ContainerBuilder();
        var executingAssembly = Assembly.GetExecutingAssembly();

        var testScreens = executingAssembly.GetTypesInherit();
        foreach (var testScreen in testScreens)
        {                   
            builder.RegisterType(testScreen).As();
        }

        var container = builder.Build();
        return container;
    }

Usage (Implicit) :

  public class MainViewModel(IEnumerable testScreens) 
  {}
