Answer 1

Complete worked example for WPF + MVVM.

Tested on MSVC 2017.

In the view:

If using ReSharper, and if the DataContext is set up properly, there will be intellisense when you hit the . after StatusIcon, i.e. it will show the properties of the enum which are Debug, Info, Warning or Error.

If using ReSharper, it will suggest the following update to the namespace in the header for the XAML file(its good like that):

xmlns:my="clr-namespace:Class.Path.MyViewModel;assembly=MyAssembly"

And the VieModel:

public enum StatusIcon
{
    Debug,
    Info,
    Warning,
    Error
}

public class MyViewModel
{
    public StatusIcon StatusIcon { get; }
}

We also use Fody for automated binding.
