Den Delimarsky explains how to apply pseudo-paged navigation in a list on Windows Phone 7.

There are several ways content can be browsed inside a list on Windows Phone. Most of the current applications (like Facebook) are using the "Load More" method - by modifying the default ItemPresenter it is possible to add an extra Button control at the end that will trigger the list update (for the list that is currently bound). This is a pretty decent method to split a large collection in smaller chunks and then access it that way. However, the situation becomes a bit more complicated when the items are already loaded and all that needs to be done is navigate through the existing set.
Den Delimarsky explains what the Mango update means to WP7 developers.
The Windows Phone 7 SDK (and the platform itself) was lacking some important features from the very beginning. It started with a pretty basic set of capabilities, but access to various shell capabilities was (and still is) pretty limited. With the Mango update, many problems will be solved and the progress that has been made shows that Microsoft actually listens to its consumers - pretty much everything people were asking for will be shipped as a part of the next update
Den Delimarsky has built a WP7 app that uses Pandora’s Artist Explorer service.

Did you know that Pandora has a dedicated web service that fetches information about the currently playing artist as well as about associated artists? It is relatively simple to use, so I decided to build a Windows Phone 7 application prototype that would display some artist information and similar artists based on the data I pass to it.
Den Delimarsky continues with his series on developing SevenDrops:
It's now time to work on the actual upload mechanism for the application. It still relies on OAuth, but as it was shown in the previous article, the foundation for it is already created.
Den Delimarsky has a short article explaining how to find the location of the IsolatedStorage in a Windows Phone 7 app.
Experienced Windows Phone 7 developers already know that there is an actual file system on the device that is similiar structure-wise to that of the actual Windows OS. A lot of the content managed by the device is stored in local spots scattered across the system that are not publicly disclosed (although since the OS image was already disassembled, most of them are known).
Den Delimarsky continues his series of articles about WP7 on Dzone with this one demonstrating how to upload your own ringtone to your WP7 device.
We all know that Windows Phone 7 doesn't carry support ringtone modifications (not by default). This can be a bit frustrating for people who don't like any of the 30 pre-loaded tunes (although it's probably hard to find one). In this article I am going to show you how it is possible to upload your own ringtone to your WP7 device. If you are not interested in the code part of the problem and detailed explanations related to it, I would recommend going to Chris Walshie's blog and downloading the ringtone installer right away.
Den Delimarsky demonstrates how to play existing media content on WP7 using the MediaElement control.
Ultimately, this article started from a simple question - how is it possible to play a media file on Windows Phone 7? There are two ways to play existing media content. The developer has to either use the system player (given that the media content is stored in the media library), or use the MediaElement control. MediaElement might be a bit tricky, but it's not that hard as it seems.
In this article, Den Delimarsky is explaining where exactly the data is stored when the user captures media content.
A PhotoCamera instance is only able to capture static images (one frame per capture). This is done via the CaptureImage method
Den Delimarsky posted a nice screencast on creating a Metro-Style Combo Box in WP7.
The WP7 SDK comes pre-loaded with all the Silverlight tools you will need to complete this task. What you end up with is a completely customizable combo box in the WP7 Metro styling.
Den Delimarsky has posted about custom photo and video camera on Windows Phone 7.
The default Windows Phone 7 doesn't exaclty come with support for custom camera viewers. Or at least this is not officially documented. It is well known that the GAC on the phone contains libraries that are not publicly accesible via Visual Studio - Microsoft.Phone.InteropServices and Microsoft.Phone.Media.Extended were floating around for quite a while. The initial approach taken to access those was through reflection, but it involved some more complex problems - with the capabilities available, some elements needed event handling and with limited Reflection capabilities on the phone, this is a real pain.
