Tom Hollander posted a blog last night discussing the refersh plans for th "Application Architecture for .NET" guide. Take a look at his blog and share your thoughts/ideas:
One of the first major deliverables produced by the patterns & practices team is Application Architecture for .NET: Designing Applications and Services. This guide is now getting close to 5 years old (it was written by Ed long before I joined the team), but unlike some of our other early deliverables, we've found that it's still surprisingly popular for its age. This is probably partly due the fact that the guide is written at a sufficiently high level for it to still be relevant despite the changes and advances to the platform.
