We are change the model in v4.0, which is currently a Technical Preview. Once this v4.0 work is completed, it will allow enablement the Shared project. As such, the shared project will have its own set of XLF files, eliminating the duplication of the XLF files.Kevin Tran commented
I tried to enable Multilingual App Toolkit for my Universal Windows project, but the menu item (under Tools) is grayed out. This is Visual Studio 2015 Community edition. However, the menu item is available in Windows 8 projects. Does anyone have the issue?
