wpbuildtarget
Build target:

  • Windows Phone OS 7.1 – can run on WP7.5 to WP8 devices
  • Windows Phone OS 8 – can run on WP8 devices only

Visual Studio 2010 supports Windows Phone OS 7.1 (Silverlight 4)
Visual Studio 2012 supports Windows Phone OS 7.1 & 8 (Silverlight 5)

Compatibility:

  • If build target is WP OS 7.1, can only use API from SDK 7.1, can’t use new API from SDK 8 even when compile with the latest SDK. Either to use WP7Toolkit or reflection method to be able to access SDK 8 API
  • If build target is WP OS 7.1, only support WVGA screen resolution only, and only WP OS 7.1 tile
  • If build target is WP OS 8, can only run on WP8 devices – so, to to support more WP devices, need to compile 2 xap files for both build target
