Question

How to implement a splash-screen using an image with alpha channels transparency/opacity in WinForms?

Answer 1

Take a look at Per Pixel Alpha Blend in C#

Answer 2

Depends on what kind of shape your image is. Is it something you can draw using code? If so you could set the forms draw region to a shape, like this:

yourForm.Region = new Region(someShape);

The shape can for example be a polygon with the same shape as your image.
