How can you stop Resharper from suggesting NET 4.6 features?
In this case it's suggesting adding ...
using static System.String;
and changing String.Format to just Format, String.IsNullOrWhiteSpaceto IsNullOrWhiteSpace, etc. 
I'm aware of adding ...
// ReSharper disable BuiltInTypeReferenceStyle
but I have to do this for all files (and that's assuming I remember and don't just let Resharper make the change)
How do you make sure it only suggests up to NET 4.5 features? (as that is what's deployed on our servers)
