Edit Question
Title
Body
This is just a curiosity question I was wondering if anyone had a good answer to: In the .NET Framework Class Library we have for example these two methods: public static IQueryable<TSource> Where<TSource>( this IQueryable<TSource> source, Expression<Func<TSource, bool>> predicate ) public static IEnumerable<TSource> Where<TSource>( this IEnumerable<TSource> source, Func<TSource, bool> predicate ) Why do they use Func<TSource, bool> instead of Predicate<TSource> ? Seems like the Predicate<TSource> is only used by List<T> and Array<T> , while Func<TSource, bool> is used by pretty much all Queryable and Enumerable methods and extension methods... what's up with that?
