We recently made a refresh of the Windows Phone documentation and samples. We've updated several samples:
We also added the following new sample that shows how to use types in the NetworkInformation namespace to get the network status of the device, mobile network and other information.
To get the latest samples go to the Code Samples page on MSDN.
In addition, we made fixes to several docs, some based on your feedback on UserVoice. For example, we added links to the camera sample from the camera docs. Please keep your feedback coming and we'll keep updating and making changes!
