Windows Phone 7 Application Certification Cheat Sheet

Published on Tuesday, August 30, 2011 6:32:00 PM UTC in Programming & Tools

In the last article, I talked about the specific requirements and recommendations regarding Windows Phone 7 iconography, including images for your application's tiles, the Marketplace, and application bar buttons. This time, I want to take it a step further and sum up all of the most important key points of the application certification requirements in the form of a cheat sheet.

Windows Phone 7 Iconography

Published on Wednesday, August 24, 2011 8:26:46 AM UTC in Programming

Every Windows Phone application has to deal with and provide a certain set of icons. The appearance and technical details of those icons are bound to specific certification requirements. Additional requirements exist for other optional places where you can use icons in your application. This article covers all of the icon guidelines and specifications relevant for a normal Windows Phone application, in particular:

Screen Orientations in Windows Phone 7

Published on Tuesday, August 16, 2011 9:30:00 PM UTC in Programming

Windows Phone 7 supports multiple screen orientations, and the built-in sensors allow the system to adjust the orientation automatically when the user rotates or tilts the device, without manual interaction. For developers, supporting these orientations and orientation changes seems pretty simple at first, but on closer inspection more and more issues need to be resolved and planned ahead.

Yesterday I stumbled upon a bewildering detail when I worked with Forms Authentication and Windows Phone 7 that cost me quite some time to fix and work around, so I decided to blog about it to save others from the same trouble.

Updated articles for "Mango"

Published on Sunday, July 31, 2011 8:38:00 PM UTC in Programming

Over the last two weeks, I went through all the articles of my "XNA for Silverlight Developers" series and made sure that they are still valid in the context of the upcoming "Mango" Update for Windows Phone 7. Since a lot of the content is XNA specific, many articles didn't require huge changes. However, some of them also cover platform specific topics like the sensor APIs (which are a bit refactored in Mango) or the application life cycle (which has been extended by the new dormant state). Those articles required adding a few paragraphs or even rewriting parts of them completely, to provide smooth explanations that fit both the RTM and Mango versions of the platform. So, if you ever felt like learning XNA on the Windows Phone, you can now do that and feel certain that you are receiving all the latest, future-proof information with these articles. Happy programming! :)
