Seems rather late to get Developers engaged for Windows 9 and Windows Phone 8 launch.  Surely we needed the Build for these platforms in early Sept, to get Apps in development for the Marketplace by Thanksgiving and xmas.  
 

This makes no sense. All the W8 stuff was covered in BUILD 2011. The sessions are all available online. You've had the last nine months to start developing apps. If you think you're constrained to the basic styles and templates that ship with the VS RC then you really haven't been looking into them.

I do wonder why HTML/JS was chosen as a platform, especially since it apparently poses the performance problems Rane mentions. Why not a native/managed app that you install locally? Wouldn't that have eased development a great deal?

One thing I would've liked to see here is clearer naming conventions for the coordinate space conversion methods. DepthImageToSkeleton, SkeletonToDepthImage, and GetColorPixelCoordinatesFromDepthPixel are all methods that deal with the conversion from one coordinate space to another but they all have a different naming style. I have to stop and think or look them up every time I use them simply because the naming is so confusing. I'd much prefer it if they were called GetDepthCoordinatesFromSkeletonSpace, GetSkeletonCoordinatesFromDepthSpace and GetColorCoordinatesFromDepthSpace, for instance. Not only are the method names then following the same naming scheme, it's also a lot clearer what they actually do as opposed to "DepthImageToSkeleton", which doesn't even have a verb. Something to consider, hopefully.

I should check out Inside Xbox more often, but I'm kind of suspecting that we're getting only a fraction of the content on there.

Best of luck, Tina!

I do the exact same thing Dan does... Dictionaries with a collection as the value type...or worse, as the key. Everytime I do it I think "I'm doing something wrong" but I can't figure out how to do it in any other way. Either that, or I just use a List<T> for everything. That collection class blogpost is going to be a great help.

A good followup post could be about how to pass collections around. FxCop always warns about using Collection<T> when passing stuff around but I can never remember why that's a good idea and when to do it.

Also, I don't get why the index in GenerateColoredBytes is calculated as ((width - x - 1) + heightOffset) * 4. Why does it start off at 1276 instead of 0?

Edit: instead of Peter Nijs's solution of making the x iteration go backwards, I changed the line

var index = ((width - x - 1) + heightOffset) * 4;

to

var index = (x + heightOffset) * 4;

Now the image is no longer mirrorred, and your x iteration can still go from 0 to width-1. The index calculation makes more sense to me this way anyway, because basically all you need is the heightOffset plus the current column, taking into account that it's four bytes per pixel. Hence, (x + heightOffset) * 4.
