Here. Normally I wouldn't point this page out, because it's *unofficial* and *unsupported*, but some folks have used the guidance on this page to fix issues with the PDC Longhorn bits, especially as related to networking. USE AT YOUR OWN RISK.

Here. Here's the third and final part of my document-centric applications in WinForms piece. In this part, I present the FileDocument component from Genghis [1] and show how it can be used in SDI and MDI applications. Enjoy [1] http://www.genghisgroup.com

Here. Under Whidbey, VC++ supports both CLR generics and C++ templates for managed code. In this post, Brandon Bray, a PM on the VC++ team, lays out the differences, while also laying out the differences between C++ templates and CLR generics in general.

Here. How cool is this? Infragistics, UI component giant, has released a technology demo of their UltraGrid control for Avalon, including source! Apparently it took 2 guys 1 month to build this control from a standing start, i.e. no previous Avalon experience. There are a bunch of limitations and Infragistics is clear that you shouldn't use this code as a template for writing your own components, but it's still fun to see. Thanks, Infragistics!

Here. If you have questions or comments about Longhorn/WinFX development, be sure to post them on one of the WinFX newsgroups. Digging through the recent activity, I'm hard-pressed to find a post that isn't addressed by a member of the appropriate MS product team. These guys are *dying* for your feedback, so post away!

Here. Mike Deem, PM on the WinFS team, lays out the core story of WinFS. It's an object store, not a file system. WinFS uses XML to describe the types of items that can be stored and then exposes .NET types for creating and finding items in the store. Also, and this is where the confusion comes from (and the codename of the technology doesn't help), when a file is created in a certain part of the system (\\localhost\DefaultStore), an item is created in the underlying store automatically. This item is used to allow the same finding code to work for things that are file-backed, like images, and for things that aren't file-backed, like contacts. Unfortunately, the story that Mike tells isn't complete yet, because custom item types can't be added using the PDC Longhorn bits, but a few of today's facts shouldn't ruin a good story of tomorrow. : )

Here. Paul Thurrot digs deeply into the PDC build of Longhorn, including impressions, screen shots and videos. Of course, since this is a developer release, the user experience isn't nearly what we plan it to be, but even developers need to know how to use the OS for which they're developing. : )

Here. Brad Abrams, a Lead PM on the WinFX team at Microsoft, *begs* for your feedback on the WinFX API: "Don't complain later if you don't help me fix it now ;-) Please comment or drop me an email or IM."
