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
{
}
}
