body: <p>I'm trying to change the top left corner icon of the winform from the default one to my icon:
  <img src="https://i.stack.imgur.com/LTnoT.png" alt="enter image description here"></p>
  
  <p>I've tried it by going to the Properties of my project, and go into Application, the set my own icon it in "Icon and Manifest". </p>
  
  <p>But after that, it still show the same old default icon. Is there something I done wrong?</p>
