Null Object Notification Example

The customer notification example shows how to keep a workflow production-safe when an optional notification provider is not configured.

The generated NullCustomerNotificationChannel implements ICustomerNotificationChannel and returns a deterministic "suppressed" status. The fluent NullObject<ICustomerNotificationChannel> wrapper is registered through IServiceCollection so importing applications can inject the fallback channel without special-case null logic.
