 After creating your custom generator, register it in `Program.cs` to replace the default implementation:
 
+{% code title="Program.cs" %}

 ```csharp
 builder.Services.AddUnique<IOrderNumberGenerator, MyOrderNumberGenerator>();
 ```

 The `AddUnique` method ensures that your custom generator replaces the default `IOrderNumberGenerator`. For more details on dependency injection, see the [Dependency Injection](dependency-injection.md) article.
