Entity Framework Include Optimized
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.
