I'm writing a small sample application for the Windows Phone 7.1 (Mango) and want to use the Combined Motion API to display the motion of the device. I need to write mock classes to be able to test my application when using the emulator which does not support all sensors of the device. I already wrote a simple mock class to simulate a compass (it just simulates a rotating device) and for the accelerometer which is actually available in the emulator. Now I would have to write a new mock object for the Motion API but I hope that I could calculate the values that are used for the Motion object

Is it possible to associate a particular file extension with my app in wp7.1? I would like to allow the users of my app to email files of a particular type to each other and then when they click on the attached email file it would launch my app so it could process the file and add it to isolated storage. No, it's not. You need a "special permission" from Microsoft to do it, that's how Adobe was allowed to do it. But there's no part of the official released SDK that allows for it. 来源： https://stackoverflow.com/questions/7068729/associate-file-extension-with-app-in-wp7-1
