I have been on the hunt for various samples to pass along to the developers I"ve been working with on the Metro style apps forums. It quickly became apparent that we have over two hundered samples and sorting through them to find a media sample that can help you out is a time consuming task. In an attempt to help the community find what they are looking for I have compiled what I hope is an all inclusive list of audio, video and camera samples from our sample drop for the CP. If you find that I'm missing something please let me know.
