Along with Windows Live "Wave 3", a new interface will be developed for Windows Live Messenger Version 9, Messenger Stuff is reporting, via an unidentified but trustworthy source, that the new version will use the Windows Presentation Foundation (WPF).
To make it easier for those who are not up to date with WPF, it was a brand new feature introduced to .NET developers in the latest version of the code (version 3). WPF allows developers to create a better user interface than what we would usually see – and an example of a program using WPF would be Yahoo! Messenger for Vista.
In short, Windows Live Messenger will now have transparency effects – but as well, Messenger Stuff is also saying that the design has not changed much but with the WPF effects integrated with the program.
