Practical Guide to Boosting Entity Framework Core Performance in .NET

Entity Framework Core (EF Core) allows .NET developers to interact with databases using C# objects and LINQ instead of raw SQL, but this convenience can mask costly operations. Common performance pitfalls include N+1 queries, excessive change tracking, unnecessary data loading, and poor pagination. The guide emphasizes that optimization is not about avoiding EF Core, but about understanding how it translates LINQ expressions into SQL and designing queries accordingly. Key strategies covered include using AsNoTracking(), projection with Select(), keyset pagination, batch operations, and async database calls. Developers are also advised to inspect generated SQL, profile query timing, and follow structured checklists for querying, tracking, and write operations.
