Unable to build a W10 UWP app in "Release" when referenced more than one API-Extension

Question

In my Windows 10 Universal app I referenced Windows Mobile Extensions for the UWP as well as Windows Desktop Extensions for the UWP. Everything works well and compiles in "Debug", but the error below appears when trying to compile in "Release". When referenced only one Extension, the app also compiles in "Release".

It seems that current Win10 SDK 10240 have some issues about release - it means .NET Native enabled - build.

This link may help you. In my cases, I've succeeded to make release build with updated .target file.
