Entity Framework Include Optimized Discover who supports this feature

Introduction

IncludeOptimized allows you to optimize the query generated by EF by executing multiple smaller queries instead of executing only one monster SQL.

Why IncludeOptimized?

Common Scenarios:

• The SQL generated by Entity Framework is too big and takes several seconds or minutes to execute.

var orders = ctx.Orders
                .Where(x => x.OrderId == myOrderID) // 1 orders, 20 columns
                .IncludeOptimized(x => x.Items) // 20 items, 10 columns
                .IncludeOptimized(x => x.DeliveredItems) // 10 items, 10 columns
                .ToList();
