I'm stupid and new to programming, so then what do I do instead if I want to use these two things together?

Generally, you find a new way, because this old way of doing it is going out of support.

In this specific case, this seems to do the trick:

public class AutoNSubstituteDataAttribute : AutoDataAttribute
    {
        public AutoNSubstituteDataAttribute()
            : base(() => new Fixture()
            .Customize(new AutoNSubstituteCustomization()))
        {
        }
    }

@mattiasnordqvist exactly. Sorry -- didn't get to this thread at time. This is the code I have been using since they changed the API. I will update the gist, thatnks.
