Creating the ViewModels

Add two new files named as ContactsViewModel and TodoViewModel in the ViewModels folder of MvxFormsMasterDetailDemo.Core project. Make them to inherit from MvxViewModel class respectively:

using MvvmCross.ViewModels;

namespace MvxFormsMasterDetailDemo.Core.ViewModels
{
    public class ContactsViewModel : MvxViewModel
    {
    }
}

using MvvmCross.ViewModels;

namespace MvxFormsMasterDetailDemo.Core.ViewModels
{
    public class TodoViewModel : MvxViewModel
    {
    }
}
