Keyless Entity Types in EF Core: Query Data Without Primary Keys
Not everything in your database needs a primary key. Sometimes, you just want to query views, stored procedures, or raw SQL results without forcing a unique identifier on them. That’s where Keyless Entity Types in EF Core come in!
If you’ve ever struggled with querying database views, reports, or read-only datasets, this feature is exactly what you need. Let’s dive into what Keyless Entity Types are, when to use them, and how to make them work in EF Core.

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.

Transactional Savepoints in EF Core: Rollback Just What You Need!
We’ve all been there—you’re halfway through a multi-step transaction, and boom! 💥 Something fails. You don’t want to roll back everything, just the part that went wrong.
That’s where Transactional Savepoints come in!
Savepoints let you partially roll back transactions, keeping the good stuff while undoing just the problematic parts. If you’ve ever wished for a “Ctrl + Z” in database operations, this is it.

Tracking Every Change: Using SaveChanges Interception for EF Core Auditing
Ever wonder who changed what and when in your database? Or maybe you’ve had that “uh-oh” moment where data was updated, but no one knows how?
Good news: EF Core has a built-in way to track changes—without modifying every query manually! SaveChanges Interception lets you hook into EF Core’s SaveChanges() pipeline and log inserts, updates, and deletes automatically.

Many-to-Many Made Easy: Mastering Relationships in EF Core
Remember when dealing with many-to-many relationships in Entity Framework felt like trying to assemble IKEA furniture without instructions? You needed an extra join entity and sometimes a sprinkle of luck to get it all working. EF Core has come to the rescue, making many-to-many relationships as easy as pie (or a fully assembled bookshelf) and giving you improved configurations that put you in the driver’s seat.

Query Tags: Debugging EF Core Like a Detective
Imagine you’re a detective working on a big case. You’ve got a pile of clues (queries), but they’re all mixed together with no labels. Which one belongs to which part of the case? Frustrating, right? That’s what debugging EF Core queries feels like without Query Tags. But with Query Tags, it’s like a breath of fresh air, relieving the frustration and making the process more manageable.
Query Tags in EF Core are like sticky notes for your SQL. They allow you to label your queries, making it significantly easier to track down problems, optimize performance, and appear as a debugging wizard.
