EF Core: ExecuteUpdate & ExecuteDelete — Why You Should Stop Looping

- 05.12.25 | 05.12.25 - ErcanOPAK

The old way:

foreach (var user in users)
    user.IsActive = false;
await ctx.SaveChangesAsync();

The modern way:

await ctx.Users.Where(x => x.IsActive)
    .ExecuteUpdateAsync(set => set.SetProperty(p => p.IsActive, false));

⚡ Benefits

  • 🚀 Single SQL statement

  • 🧼 No tracking overhead

  • 💾 Saves CPU + DB roundtrips
