Imagine you’re moving to a new house. You could pack only the essentials and enjoy a stress-free move, or you could drag everything you own—grandma’s old lamp, that broken treadmill, and a box labeled “random cables.” This analogy of moving to query projection makes the concept familiar and relevant. Moving with all that clutter? Nightmare.
The same applies to your EF Core queries. Why fetch every column in a table when all you need is a handful of them? That’s where query projection comes in. It’s all about keeping your data lean, clean, and most importantly, efficient. Embracing query projection is like optimizing your coding practices for maximum efficiency.

If you’ve ever gone grocery shopping while hungry, you know how easy it is to end up with more than you need. The same thing happens in EF Core when you’re too eager with your Include statements—you fetch all the data, even the stuff you don’t need, and suddenly, your app feels sluggish. That’s where Explicit Includes comes in, allowing you to fetch only what you need when needed, making your development process more efficient. Think of it as grocery shopping with a list, but for your code.

Picture this: You’re hosting a dinner party, and instead of serving everyone a delicious buffet, you deliver each dish one at a time to every guest. When dessert arrives, everyone’s too tired (or annoyed) to enjoy it. My friends, this is the problem with single queries in EF Core when they fetch complex relationships. Enter Split Queries, the life of your EF Core dinner party.

So, you’ve embraced Entity Framework Core, and life’s been good. No more handcrafting SQL for every little query. But what happens when EF Core’s LINQ magic isn’t entirely cutting it? Maybe you need something specific, like a stored procedure or a complex SQL query that LINQ doesn’t handle elegantly. That’s where FromSql swoops in to save the day.

Imagine you’re running a restaurant. Every time a customer orders, you buy a brand-new frying pan, use it once, and toss it out. Sounds absurd, right? But that’s essentially what happens in EF Core when you create a new DbContext for every request. It’s wasteful, slow, and totally unnecessary. Enter DbContext Pooling: the genius way to reuse those frying pans—err, contexts—and turbocharge your app’s performance.
