EF 如何同时加载集合属性中元素的属性

标题不太好写

A Have List
B have C

EF6:
dbConte[align=right]xt.Set().Include(a => a.Bs).Include(a => a.Bs.Select(b => b.C))
EF core:
var customers = context.Company
.Include(i => i.Manager )
.ThenInclude(a => a.ClientMessage )
.ToList();

Other:
Lazy模式，Include不起作用，只有关闭Lazy模式后（去掉virtual或显式关闭Lazy模式）则Include有效
