Resources File in .NET Standard (1.4) with New csproj

I'm developing an application targeting .NET Standard 1.4, using the new csproj style (not project.json), and trying to get a localizable resources file to become available throughout the project.

I get compiler errors when including a resources file currently, similar to 'Resources' does not contain a definition for 'X'

The csproj automatically includes the resources file as follows:

True
True
Resources.resx

ResXFileCodeGenerator
Resources.Designer.cs


Did it miss a step in the generation? Why can't I access any of the members of my resources file throughout the assembly?
