NotifyOfProperty change from inside of ObservableCollection

How can I trigger NotifyOfPropertyChange by changing property of item inside of ObservableCollection?

Currently I am assigning null to ObservableCollection and then the original value. However, I don’t think this is a proper solution.

ObservableCollection<Item> temp = Collection;
Collection = null;
Collection = temp;

I have also tried to implement INotifyPropertyChanged interface, but it didn’t work

public class Item : INotifyPropertyChanged
{
    public string Name { get; set; }

    public event PropertyChangedEventHandler? PropertyChanged;
}

>Solution :

Implementing INotifyPropertyChanged is not enough, you actually have to use it.

See INotifyPropertyChanged Interface documentation for an example.

using System.ComponentModel;
using System.Runtime.CompilerServices;

public class Item : INotifyPropertyChanged
{
    public event PropertyChangedEventHandler? PropertyChanged;

    // This method is called by the Set accessor of each property.  
    // The CallerMemberName attribute that is applied to the optional propertyName  
    // parameter causes the property name of the caller to be substituted as an argument.  
    private void NotifyPropertyChanged([CallerMemberName] String propertyName = "")
    {
        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
    }


    private string m_name = "";

    public string Name
    {
        get
        {
            return m_name;
        }
        set
        {
            if (m_name != value)
            {
                m_name = value;
                NotifyPropertyChanged();
            }
        }
    }
}
