我该怎么做呢？

如果您提供更多详细信息，我们可以帮助您开发更具体的解决方案。但这大概就是你需要做的：

var query = from e in context.Employees
            join b in context.Bids on e.ID equals b.UserId
            group new { e, b } by e.ID into g
            select new
            { 
              Employee = g.FirstOrDefault().e,
              AverageBid = g.Average(x => x.b.Amount),
            };

到目前为止你有试过什么吗？

var query = from e in context.Employees
            join b in context.Bids on e.ID equals b.UserId
            group new { e, b } by e.ID into g
            select new
            { 
              Employee = g.FirstOrDefault().e,
              AverageBid = g.Average(x => x.b.Amount),
            };
