15.5.26-linq to ef多级外链查询

方法一：

var query = db.Test.Where(x => true)
    .Include(x => x.ColB.Select(s => s.ColBRelated))
    .Include(x => x.ColC)

方法二：

var query = db.Test.Where(x => true);
query = query.Include("ColB");
query = query.Include("ColC");
query = query.Include("ColB.ColBRelated");

多级外链查询，test有外联数据colB和colC，colB有外链数据ColBRelated。
