I used to use a lot Adobe Fireworks for web design work and actually always preferred it to Photoshop to create application mockups and page layouts (I am a big fan of vector graphics and grew up using Corel Draw A LOT).

Now for the joy of all Fireworks fans, Infragistics released a plug in that allows to “convert artwork created in the Fireworks software to the new XAML format used to declaratively define user interfaces in Windows Presentation Foundation (WPF)” (and I will add Silverlight although I guess that would need to be tested as Silverlight is a subset of WPF so some features may not work with it).

You can also find additional info on Grant Hinkson’s post on the Adobe Devnet.

Not sure if this will work on Macs though, has anybody tried it?
