Performance

Two real production scenarios on a 1-million-row catalog - a tiered pricing promotion and a live CSV feed import - with numbers measured on camera: where a hand-rolled EF Core loop is fine, and where BulkUpdate, BulkMerge, and BulkSynchronize from Entity Framework Extensions turn 51 seconds into 12.

Updating or deleting many rows by loading them, changing them in a loop, and calling SaveChanges is the slow path. ExecuteUpdate and ExecuteDelete send one SQL statement and skip the change tracker entirely.

Why offset pagination falls apart at scale, and how cursor pagination keeps your API fast with millions of rows.

.NET 10 file-based apps just changed how we write scripts in C# - no .csproj, no boilerplate, just code.

How to replace a bloated OnModelCreating method with separate entity configuration classes using IEntityTypeConfiguration<T>.

Stored procedures - when raw SQL belongs in your database, not your C# code.

Your app is making 1501 SQL queries per request - and the code looks completely fine. Learn how to identify and fix the N+1 problem and Cartesian explosion in EF Core.

Learn how to replace slow EF Core bulk operations with Entity Framework Extensions for up to 39x faster inserts, updates, deletes, and merges.
