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 take several seconds or minutes to be executed.
