为什么从不调用析构函数？

Question

From what I understand the destructor is called when a class instance goes out of scope and the garbage collector makes a pass. In the code below the destructor is never called. What's going on?

while (true)
{
  var Thing1 = new Thing();
  await Task.Delay(100);
}

class Thing
{
  ~Thing()
  {
    Console.WriteLine("Destructed");
  }
}

With this code I managed to call the Finalizer . I guess, the garbage collector needs the heap to fill up to a certain point before it makes a pass.

while (true)
{
  var Thing1 = new Thing();
  await Task.Delay(100);
}

class Thing
{
  public List<int> List { get; } = new(1000000);

  ~Thing()
  {
    Console.WriteLine("Destructed");
  }
}
