Choosing between WPF and Windows Forms Applications

Now I'm in position to start a new project. Until now I always choose the WFA.

Now I want to know what is the creteria of choosing WPF or WFA.

What is the motivation for choose.

ADDITIONAL INFORMATIONS

The project refers开发者_如何学JAVA to:

• Handle incoming mails
• Crate a suitable invironment for the user (receiver)
• Following up the process in mails
• Closing the actions

really, just use wpf, as it's better in all areas.. the only reason i'd go for winforms is you don't have the time to learn wpf..

Do you want to have the application be supported by or easily migrated to upcoming .NET versions? If yes, choose WPF.
