How do you set a custom theme for a .NET application?

Much as the title says, I am wondering how to style a program like Photoshop CS4 or Autodesk Maya 2011. These programs are styled to where the UI looks completely custom. Right now I am u开发者_StackOverflow中文版sing C# to program, but I can easily switch to C++ and WinAPI if it is easier. I have done multiple google searches for styling controls in C#, but there are seemingly no accurate results.

Much thanks for any help, -Thomas

If you using C#, WPF is a way to go, to make some custom UI. WinForms are not so modifiable.

This is a no easy task. DevXpress offer a wide range of skins with their components, so does Telerik.

There is a free library (without source) at Skybound, however this one is pretty old and not being developed anymore.
