您正在创建通用Windows应用程序,应该创建Windows Phone 8.1应用程序。
Is your device registered as a Developer Device? In the Phone SDK is an App "Windows Phone Deveveloper Registration". You have to enable your device as Developer Device. And, yes, your App must be a Universal App for (8.1 or 10, depending on your Phone OS Version).
