Not much time for blogging lately. Sigh. Anyway, from my previous post, it should be clear that i am working on a WP7 project. The app i am working on should be up in the marketplace at the end of October when the phones will be released.

Here are a couple of comments related to WP7 development :

- don’t treat it as a toy. If you approach the platform with the “desktop developer” mindset you will fail. Hard.

- think a lot about usability when designing the UI of a mobile app.

- understand the app lifecycle and the various performance tradeoffs.

- it’s Silverlight 3 with phone specific additions. You can use some stuff from Silverlight toolkit but don’t count on too many things working out of the box. Look into panorama & pivot controls. They are very useful in a lot of UI scenarios.

- the “runtime” (compact CLR + Silverlight) is pretty fast. For “regular” stuff you’ll never need to worry about performance.
