Yesterday, I had the privilege to watch a bit of the Jumpstart training on Windows Phone 7 with Rob Miles and Andy Wigley after work, even though it was two hours,.
I did gets some great tips on creating great applications especially on advice when creating a “light version” of an application rather than the trail mode as it entices them to purchase the full application more via a link rather than being put off by the word “trial” with its limited features that it imposes.
Other tips were to make full use of the application submissions as a dedicated app published reviewer from Microsoft reviews and takes note of if the application is deemed worthy to be published, so only 100 application attempts for publishing are free, after you need to pay for publishing your app, this is for the free version of your application that is.
Here is some screenshots made from the online event.
