VS2013 is using a different ARM compiler and binaries created with this compiler are not compatible with binaries created by the previous version of the ARM compiler, so libraries included in SDKs rolled for versions prior to VS2013 will never work on VS2013. Either use VS2008 for application targeting that SDK, or re-roll the SDK using VS2013 (but the device image will also have to be changed to WEC2013 of course!).
PS. Apologies for the late response; your comment was marked as spam unfortunately..
