Form header/border looks different when running

I am not sure how to show pictures in here but I have a question about the actual forms…I have a form created in VS2019…I like how it looks but when I run it, the form looks different in terms of the header and border etc…I am not sure why and how I can set it so that the form when run looks like the form in design mode…the labels etc are all fine…its just the actual form itself.

if you can see the image, the image on the left is the design in VS and the image on the right is when its running. I would like to be able to keep the design image form.

thanks

Gerard
