我知道我可以更深入地使用ThenIncludeEager Loading加载相关数据，如下例所示

//Eager Loading
var publisher = await _context.Publishers
                              .Include(pub => pub.Books)
                                  .ThenInclude(book => book.Sales)
                              .Include(pub => pub.Users)
                              .Where(pub => pub.PubId == id)
                              .FirstOrDefaultAsync();

如何在显式加载中编写相同的查询？Sales在下面的情况下，如何在不循环阅读书籍的情况下加载数据？

//Explicit Loading
var publisher = await _context.Publishers
                              .SingleAsync(pub => pub.PubId == id);

_context.Entry(publisher)
        .Collection(pub => pub.Books)
        .Load();
                 
_context.Entry(publisher)
        .Collection(pub => pub.Users)                
        .Load();
