Parent task does not wait for child task to complete

Question

So here is my code

Task parent = Task.Run(() =>
{
    var result = new int[3];

    TaskFactory tf = new TaskFactory(TaskCreationOptions.Atta         


        

Answer 1

In Task.Run's documentation, you'll find that it specifies

Its CreationOptions property value is TaskCreationOptions.DenyChildAttach.

So, even though you specify TaskCreationOptions.AttachedToParent, it is ignored.
