EntityFramework string Include() a child property

Question

I had an Include method like so

public static IQueryable<SlideSet> IncludeParameters(this IDbSet<SlideSet> storage) {
    return storage.Include(ss => ss.Params.Select(x => x.Parameter));
}

I am cleaning up my domain model and it no longer makes sense to have SlideSet.Params be public.

I know that there is a form of IDbSet<>.Include() that takes a string parameter. What is the syntax for using a string while descending into the child property like this?

btw, for those who are wondering, I'm pretty sure

return storage.Include(ss => ss.Params.Select(x => x.Parameter));

is identical to

return storage.Include(ss => ss.Params.Include(x => x.Parameter));

Just use .:

return storage.Include("Params.Parameter");

Ok thanks, its kind of a big refactoring and I wanted to make sure it was possible before forging ahead.

For completeness sake, the docs for IQueryable.Inclue mention this, just not the docs for the more specific IDbset.Include where I was looking... Ugh.
