This is a workaround to fix ILT0005. If you encounter this error using a non-english UI for Visual Studio 2015 Update 2 and trying to build a release version of your UWP app like I did
ILT0005: "C:\Program Files (x86)\MSBuild\Microsoft\.NetNative\x86\ilc\Tools\nutc_driver.exe @"D:\src\FileTouch\FileTouch\obj\x86\Release\ilc\intermediate\MDIL\FileTouch.rsp"" hat den Exitcode -1073740791 zurückgegeben
then you have to install the english language pack and use it to be able to create the release build. Actually this bug is part of the .NET native tool chain.
Language Pack Installation
Simple go to Tools / Options / International Settings and select English (of course this steps have to be taken in your language you are using). If you haven’t installed the pack simply follow this link and install it.
I hope that this bug will be fixed in the near future, I just encountered it by accident as I usually don’t use native UI for my dev environments.
