ServiceCollectionExtensions

Examples

ServiceCollectionExtensions provides registration methods for IServiceCollection that support multi-contract resolution, typed options, and bulk post-configuration. This example defines an OrdersMessageHandler implementing both IMessageHandler<OrdersChannel> and IDependencyInjectionMarker<OrdersChannel>, then registers it with various lifecycle options using Add, TryAdd, and TryConfigure overloads including scoped and singleton lifetimes. It also demonstrates PostConfigureAllOf<HandlerOptions> for bulk configuration of options instances. After building the service provider and creating a scope, the concrete handler, typed contract, and marker are resolved and compared by reference. Console output confirms that all three resolve to the same instance and that HandlerOptions.Label is correctly set to "post-configured".
