Aaron has posted a good primer on the various version checks used in the WiX setup files which are a part of the Visual Studio templates and Z sample application shipped in the SDK. If you are using either one of these as the basis for your installer you will want to read http://blogs.msdn.com/astebner/archive/2008/07/24/8770953.aspx. Thanks, Aaron...!

Damian Mehers in Switzerland has created two great screenscasts outlining how he created the BBC Radio experience.

Part 1 is a great companion to the Step-By-Step walkthrough in the SDK. Damian provides an excellent tour of the most commonly used application template which novices to Media Center development will find very helpful.

Part 2 demonstrates how Damian modified the template to achieve the BBC Radio solution.

Thanks for taking the time to put these together for the community, Damian -- they are wonderful learning resources!

We put the template support in for Visual Studio 2008 towards the very end of the 5.3 development cycle as a 'bonus' to fulfill community requests -- you'll notice we don't even mention it in the What's New section of the SDK documentation at all since we didn't know the street date for Visual Studio 2008.

There are three templates which ship in the 5.3 version:

Windows Media Center Application
A project for creating a Windows Media Center Application containing a page with four buttons which invoke a Media Center dialog box.

Windows Media Center Application - Background
A project for creating a Windows Media Center Background Application.

Windows Media Center Application - Fundamental
A project for creating a Windows Media Center Application containing the minimum code and markup required.

It just so happens that Visual Studio 2008 released to the general public a day or two before we released, so I've been scrambling to test out the SDK install on all sorts of permutations of Visual Studio installations -- the surface area for this testing is quite large when you look at the fact all of them can peacefully coexist with side by side installs. Last night we found an issue where one of the templates (the first one in the list above) isn't available in Visual Studio 2008 if the only development tool you have installed is a Visual Studio 2008 SKU.

Select one of the following to resolve...

• Make sure you have a Visual Studio 2005 SKU installed (including any Express Edition) in addition to Visual Studio 2008 prior to installing the SDK.
• Run a repair of the Windows Media Center SDK 5.3 if you've already got it and a Visual Studio 2008 SKU installed and are installing a Visual Studio 2005 SKU second.

Working through the last revision of the SDK I found it was really hard to discern the development environment for successfully developing a Windows Media Center application -- mainly because you can't read what we write before installing the SDK...! :-)

So, let me take a moment to give you what I consider the bare minimum install set for a development machine in the order they should be installed.

An updated version of the Windows Media Center Software Development Kit is now available for download from http://www.microsoft.com/downloads/details.aspx?familyid=a43ea0b7-b85f-4612-aa08-3bf128c5873e&displaylang=en. This is the same link as before so no need to change your bookmarks. These links also persist in the navigation section at http://blog.mediacentersandbox.com/.

Here is a list of what's new or changed with this release...

MCML Preview Tool Automation Model
An improved automation model allows a tools developer to load an MCML file, refresh the current view, and close or get the position and size of the current instance. New command-line switches specify a folder to watch and automatically refresh when any resource in the folder changes.

Changes to the MCML Preview Tool Launcher
The improved MCML Preview Tool Launcher takes advantage of the new MCML Preview Tool automation model and command-line switches.

Additional Documentation on Animations in MCML

Check out the new or improved documentation on these topics:

• Working with Animations in MCML
• Using Keyframes in Animation
• Applying Interpolations to Keyframes
• Setting the Weight on Interpolations
• Playing Different Types of Animations in Response to Events

MCML Animation Explorer
MCML Animation Explorer is a new tool that helps developers learn animation in MCML. Instead of writing XML you can work with a bunch of knobs and switches in a graphical user interface and see the resulting MCML as well as the visuals in the MCML Preview Tool.

New Visual Studio Templates
The following templates have been added for C#:

• The Windows Media Center Application – Background template creates a project for a Windows Media Center background application.
• The Windows Media Center Application – Fundamental template creates a project that provides a basic framework for creating a Windows Media Center application.

Visual Studio 2008 Support
The application templates now work with Visual Studio 2008.

Deprecated Features
The following platform features have been deprecated with this release:

• Hosting for Microsoft .NET Framework 3.0 Extensible Application Markup Language (XAML) browser applications (XBAPs).
• The Triple-tap / Soft-keyboard ActiveX control for hosted HTML applications.
• Support for using alternative shells to run and host HTML applications.

This sample would be classified in the 'fun' category of neat things you can do with MCML and animations. Enjoy...!

PowerPlaylist adds a custom Start Menu strip with up to five tiles to Windows Media Center in Windows Vista. Each tile represents an audio, slideshow and / or visualization combination which will start when the tile is selected. PowerPlaylist is very customizable by the consumer using the PowerPlaylist Editor, including the title of the custom Start Menu strip and the name, image, audio source, slideshow folder and visualization for each tile. It's over on CodePlex.com so has full source code available with the Microsoft Permissive License.

Check it out at http://www.codeplex.com/powerplaylist.

The day after the geek dinner Scott Hanselman and I sat down to chat about developing for Windows Media Center for Hanselminutes 82. The result is a pretty nice introduction to what you need for development, the tools included in the SDK, some of the samples which are included in the SDK and some basic beginner concepts. Here is a detailed list of links which corresponds to the various topics we covered during the podcast.

I'm pleased to announce the addition of Steven Harding to our Community Dev Expert team joining Niall and Andrew.

Steven is the author of Yougle, MoreWithMyMusic and EMUCenter for Windows Media Center in Windows Vista and several other experiences built for prior versions of Windows Media Center. He also has created a poker game timer which tells you the current blinds, the current ante and how long until they next go up -- all with text-to-speech announcements of blind increases and warnings when they are getting near.

In addition, he is a contributor to the The Digital Lifestyle Developer Blog (part of the excellent group of resources made available by Ian Dixon over at http://thedigitallifestyle.com/cs/).

Steven has contributed over 400 posts to our developer forums over at http://discuss.mediacentersandbox.com making him one of the most prolific and helpful individuals in the community. His passion for Windows Media Center and the platform shine through in his postings and advocacy on behalf of other developers.

You can identify Steven in the forums by his rather esoteric alias of IgnoranceIsBliss in the forums (perhaps he'll comment here on how he decided on that moniker) as well as a new banner in his postings that looks like this:

Congratulations, Steven -- certainly well deserved.

This sample demonstrates how to use the PlaySound Element with the Timer Class to create a playback loop which does not use the PlayMedia Method and therefore is not reflected in the Windows Media Center user experience.
