I'll be checking out (a bit seriously this time) the December 2008 revision of Windows Presentation Foundation Application Quality Guide. I'm a big fan of quality and patterned development (see this as enjoying being in control of things) and whenever I see any initiative regarding this matter I tend to give it some attention whenever I can. The fact that I'm currently developing with WPF, Prism and MEF definitely leads me towards this behaviour, whether it's for my own professional and technical training, nor for the enrichment of the skills of my team.
This Quality Guide is 100% focused on WPF. It is a work-in-progress document that explains the in's and out's of WPF in a quality assurance fashion, from architecture, testing concerns, design, security, localization, best practices and so forth. It ends with some links to online resources, tools and contacts that you can take advantage of.
Yu can check out the online version here, and the full document can be downloaded here. It's about 77 pages, and it is currently in version 0.4.
Enjoy...
