I am happy to announce that I have open sourced and released my first Windows Phone 7 Application to Marketplace a few days back. You can get the source code from http://gtasksplus.codeplex.... I will also do a series of few blog posts to take you all through developing the application from scratch. Check back regularly. Sorry for not posting anything for a long time, I have been concentrating on learning some new things and did not really get a chance to continue blogging. Will try and be consistent...
