I'm fixing a problem with the linked source; for now, you'll need to download and build the project (see link below.)

The Demo

Some of you may recall a very similar demo from MIX08 done with WPF.  When the internal builds of SL3 included the new Perspective 3D feature as well as custom pixel shader support, I thought, "I wonder how hard it would be to replicate the WPF demo?"  Turns out it wasn't very hard.

While visually they're very similar, the mechanism for creating the 3D look is different.  WPF uses a 3D model and 3D rendering.  In SL3, it's a perspective transform exposed as the Projection property on UIElement.  It's of type ProjectionPlane which allows you to apply a perspective transform by specifying rotations about the X, Y and Z axes.

·         SL3 Projection Property

o   The 3D effect was created with UIElement.Projection property.

·         Custom Effects

o   I used the ones for WPF found on codeplex.  These are written in HLSL (looks very similar to C.)  I added some custom properties to these exposed on the defined Effects classes (e.g. I created the “ColorKey” property on the ColorKeyAlphaEffect so that you can dynamically pick which color to key from.)  If you’re going to edit or create any of your own effects, you’ll need the Microsoft DirectX SDK to compile the shaders.

·         Custom Physics Model

o   I built a very simple physics model to create the bounce effect.  I could have used the animation easing functions but I geeked out and used some long lost stuff I learned in college.)

·         DataGrid & Validation

o   Aside from video and images, the demo shows how you can apply the bouncy effect to standard controls.  Inside the DataGrid, I took advantage of some of the new validation support in SL (try entering a 3 or more letters for the State and press “tab”.)

Net, you get something that looks like the following (RippleEffect applied):

And for pure gratuitousness, double-click on the top 5-10% of the top edge of the floating frame; you should get a nice little flip:

Otherwise, I’ve zipped up the entire solution (after doing some simplification) and made it available for download.  If you have any questions about the code, let me knowJ

Since I'm helping organize the PDC this year, I just got to check it out (I'm actually writing this as I'm sitting in one of the many weekly PDC meetings that I attend) - they are HOT!  Not only are the drives themselves sweet - PDC-branded, black, sleek - we hope that a single, USB drive for your bits will be more convenient than a handful of DVD's.  Plus, you get to re-use it:)  Get a peek at it in this Channel 9 video.

So, how do you get one of these?  Register and attend the PDC - you've still got time!!

.NET 3.5 SP1 includes some excellent improvements in cold startup for WPF applications.  These aren't just 3-5% improvements; these are 20, 30 and even 40%+ improvements!  The best part is that applications don't need to do anything to get the benefit in most cases!  Imagine, one day your application just got significantly faster to start!

The second improvement I'm very excited about is the .NET 3.5 SP1 Client Profile.  Basically, this is a subset of .NET 3.5 SP1 targeted at those building client applications.  It weighs in at around 26.5 MB, a nearly 86% reduction from the 197 MB of the entire Framework.  Additionally, it allows for a customized install experience of the Framework!  The sum is dramatically improved install experiences for Windows applications built using .NET!

From the information I have it appears that a significant number of assemblies are being ngen'd after reboot.  The NGEN'ing itself can use a significant number of CPU cycles but if you happen to be running .NET applications before the NGEN'ing completes you'll likely see the results of JIT'ing as well.  The overall experience can be very poor performance.  Once NGEN'ing is complete, though, the problem shouldn't continue.  The right people are looking into the issue now; if/when I've got new info I'll post.
