You need add two parts for your project:
Part1 :Add NotifyObject.cs

 public class NotifyObject : INotifyPropertyChanged  
    {  
        public event PropertyChangedEventHandler PropertyChanged;  
        public void RaisePropertyChanged(string propertyName)  
        {  
            if (PropertyChanged != null)  
            {  
                PropertyChanged(this, new PropertyChangedEventArgs(propertyName));  
            }  
        }  
    }  

Part2 : Make the MainWindowViewModel.cs inherits from NotifyObject,delete public ObservableCollection<User> Users { get; set; } and add like below:

class MainWindowViewModel:NotifyObject   
    {  
  
        //delete public ObservableCollection<User> Users { get; set; }  
  
        private ObservableCollection<User> _users;  
        public ObservableCollection<User> Users  
        {  
            get { return _users; }  
            set  
            {  
                if (_users != value)  
                {  
                    _users = value;  
                    RaisePropertyChanged("Users");  
                }  
            }  
        }  

Then you can get the data in the main UI like this:
