C# AutoMapper does not copy Collections

What's the mistake in the following code, when I try to copy on List to an other? The count of list is always 0.

using (WeldingEntities db = new WeldingEntities())
{
    var query = db.Users.Select(x => x).ToList();
        var config = new MapperConfiguration(cfg => cfg.CreateMap<List<User>, List<SimpleUser>>());
        var mapper = config.CreateMapper();
        var list = mapper.Map<List<SimpleUser>>(query);
        return list;
}

You don't specify the collection type in your map definition. You just need to specify the individual type and automapper can figure out collection mapping on its own.

var config = new MapperConfiguration(cfg => cfg.CreateMap<User, SimpleUser>());

See docs for more info on the collection types that are supported.
