Please note that as of October 24, 2014, we will be archiving some of the Nokia Developer discussion boards. The Nokia Asha and Nokia X sections will remain open for continued use. The "Windows Phone/Lumia" and "Other Platforms" sections will become read-only. For your Windows Phone development questions, we invite you to visit the Microsoft Developer Network (MSDN) discussion forums. For Near Field Communication related topics, we recommend using the Developing for Windows Phone forum.
