Xamarin Froms, Visual Studio 2017, String Localization

Hey guys

I was using so far Visual Studio 2015 to develop apps with Xamarin Forms, PCL

I recently downloaded Visual Studio 2017 for the same purpose

Unfortunately, I can't create a resources file(.resx) because I simply can't find this kind of file when I'm trying to add a new item to my project

I tried to add one from my existing projects, but i get the error "Build action 'PRIResource' is not supported by one or more of the project's targets"

Is there a new way to Localize strings in Visual Studio 2017?
