whats the use of Events in Domain folder?

[avireddymatta]

Hi,
I am try to understand this architecture, everything is new like CQRS and other things ( more used to repo pattern)

I got the CQRS pattern implementation

1# whats the use of Events in Domain folder? with out those events can't I do the Command Actions ( Create, Update, Delete)

             public class TodoItemCompletedEvent : BaseEvent
              {
                  public TodoItemCompletedEvent(TodoItem item)
                  {
                      Item = item;
                  }
              
                  public TodoItem Item { get; }
              } 

2# I see in the DbContext, DispatchDomainEvents what it does? ( does this executes Events in Domain, all i see is constructor and class property assignment)

3# why do we need "Done" property in Entities

            public bool Done
            {
                get => _done;
                set
                {
                    if (value == true && _done == false)
                    {
                        AddDomainEvent(new TodoItemCompletedEvent(this));
                    }
        
                    _done = value;
                }
            }
