How to do grouping, aggregation (Sum, Count, Max, Min) via LINQ?

var groupedData = context.Orders

.GroupBy(o => o.CustomerId)

.Select(g => new

{

CustomerId = g.Key,

TotalOrders = g.Count(),

TotalAmount = g.Sum(o => o.Amount),

MaxAmount = g.Max(o => o.Amount),

MinAmount = g.Min(o => o.Amount)

});
