If you have not tried the Windows Phone App Studio, you should give it a try. It is a simple online tool that allows anyone to build a Windows Phone app with a few clicks of a button.
It predominantly relies on hooking up RSS Feeds, YouTube channels or seaches, Bing searches and Flickr queries. There are some other features such as adding HTML or a DataCollection to store data, all of which serve its purpose, to have the ability to create a quick and simple app.
In Part 2 we will look into some of the limitations of Windows Phone App Studio and look at a few easy ways to correct them. If you have not looked over Part 1, you can and follow along.
I love the App Studio - I have used it for three apps but my favorite is Rocket Launches. Instead of RSS I use the database option that I can add to and modify from within App Studio.
I also love the App Studio...
@richard - take a look at the azure tut, use mobile services to make your data collection a bit more robust
