In this post, I’m going to assume you now understand how to write cross-tier validation methods and attributes. The code shown should be saved in a .shared.cs file so that it is automatically compiled into your Silverlight project.

I am currently working on four video/tutorial series:

• Getting Started with Silverlight
• Windows Phone 7 Programming
• Blend for Developers
• The HyperVideo Platform project. 

Tim also shows how he extended the SMF implementation and created a player to suit his specific needs (including not using DVR, among other features). He cracks the code open and shows how he extended the SMF to add custom features so the video does not start until it has a chance to buffer (about 3 seconds). Tim also added the ability to pass a parameter to the SMF player to indicate if it should automatically load the video or if the video should use smooth streaming.

Whoa! I am getting a lot of questions on data validation. This warrants an article. Of course, we have many choices. Some are prescriptive, some are simple, and some are just not reliable.

For now, I will just limit data entry to valid numbers. That doesn’t mean Char.IsNumeric. Commas and periods are valid. I also have to remember valid keys like shift, backspace, and tab.

The article describes how to create a powerful Windows Phone 7 catalogue presentation which downloads the actual data from Internet and displays them in an intuitive and innovative way on a Windows Phone 7 device.The application we are about to create in this article will consist of two parts:

• Web Service – runs at server – provides data for the application
• Shopping Mall – a WP7 application visualizing data to the user through its GUI (rendered with the help of Bee Mobile Metropolis).

Mike Taulty shares his experience with diagnosing a Silverlight app using IE9's Network Capture.

Yesterday, I was doing a little work with Silverlight and I’ve got this little sample that I’m working on;

and one of the things that it does it talk XML or JSON to a back-end service depending on the value of the ComboBox up in the top right hand area.

I wanted to do a little diagnosing around this and, usually, I turn to Fiddler for this kind of diagnostic work but I’m running the IE9 RTM (download) and so I thought I’d use the network capture in there rather than rely on Fiddler.
