I am trying to make a transparent application, but the results come out with grainy edges, like this example in the image below. Is there any way to remove this green outline?

        Me.BackColor = LimeGreen
        Me.TransparencyKey = Me.BackColor

Error SS:           Green outline

    There are a few methods, this is one of the more common: [Windows Form Transparent Background Image](https://stackoverflow.com/a/33531201/7444103). – Jimi Jan 14 '20 at 20:49

A couple ways:

  1. Use a background color that is very near to the while border color. Then the thin outline will be much less visible.

  2. Use Layered Windows.
