Ribbon based GUI - Winforms vs WPF

For a new project, I'm writing an administrative tool as a client software. So far, I've only written some small winforms application with a 'old-lookin' GUI.

I'm thinking of something fresh, new looking like ribbon based design.

The questions that come into my mind are:

1) Should I prefer WPF over Winforms for a ribbon based 开发者_运维问答GUI(though I've never touched WPF before)

2) Are there any recommendations for free ribbon controls? I've found out that Microsoft seems to have this ribbon license, but I still don't get it. Do they offer a full functional ribbon based control? If yes, Winforms or WPF?

Visit http://fluent.codeplex.com/ to download a free ribbon for WPF. This ribbon has the style of the Office 2010 ribbon, and I've already used it in one of my apps. The download also has a lot of examples on how to implement the ribbon into a WPF application.

As far as switching from WinForms to WPF, yes it's a big learning curve, but at some point you should take the dive and start learning it. You'll be glad you did.
