Building universal app for windows 10

Hi, whenever i try to build project for windows 10 (windows store > windows 10 universal app)
i get a lot of errors after opening the project solution, and it shows i am missing a lot of references

I tried it even on a new and empty unity project, with nothing but a canvas on it, still got errors.
Is there something i need to do that i’m missing?
or does it just not work yet?

Known issue that VS2015 RTM (final) changed things since RC (which 5.2 was being developed against).
We’re working on fixing it for final release of Unity still.
