Grouping Smarter: LINQ GroupBy Enhancements in EF Core
Grouping data in Entity Framework Core (EF Core) used to feel a little… clunky. Sometimes, LINQ’s GroupBy() worked beautifully in-memory but got lost in translation when executing SQL queries. You’d write a simple GroupBy(), and EF Core would pull all the data into memory before doing the grouping—not good!
But things are getting smarter and more efficient in recent versions of EF Core! With LINQ GroupBy enhancements, EF Core now translates more grouping operations into optimized SQL queries, saving memory and improving performance.
