Extension method "Select" is only usable on concrete PagedList class #112

The current signature of the "Select" extension method is:

IPagedList<TResult> Select<TSource, TResult>(this PagedList<TSource> source, Func<TSource, TResult> selector)

As this is an extension of PagedList<T> rather than IPagedList<T> it is not visible as an extension method for the interface.

Meaning the following code compiles but results in IEnumerable<T> rather than the desired IPagedList<T>.

var pagedList = queryable.ToPagedList(pageNumber, pageSize).Select(x => x.SomeProperty);
