About this library

ServiceResolver.GenericHost is an abstract library for .NET generic host, which uses ServiceResolver.Ioc library.

Take this example defining a new IServiceRegisterProvider implementation (or other third party IServiceRegisterProvider implementation).

class CustomServiceRegisterProvider : IServiceRegisterProvider { public CustomServiceRegisterProvider(CustomServiceRegisterDescriptor descriptor) { // coding for setup. } // your custom implementation .. }

Configuration for console applications (Net Core, Net 6 or higher)

IHostBuilder configuration

The extension method UseServiceResolver has as input the ServiceRegisterOptions instance.

var hostBuilder = Host.CreateDefaultBuilder(args) // custom extension method to use for integration. .UseServiceResolver(new ServiceRegisterOptions<IServiceRegisterProvider> { // a factory used to create your service register provider OnCreating = collection => { return new CustomServiceRegisterProvider(new CustomServiceRegisterDescriptor()); }, // (optional) // an action used to prepare (if needed) your IServiceCollection. BeforeRegistering = collection => { // your IServiceCollection registrations or integrations }, // an action used to register your services. OnRegistering = provider => { // example: provider.Register<StringBuilder>(() => new StringBuilder("hello world..")); }, // (optional) // an action used to executes custom action at the end of all previous steps. AfterBuildingProvider = provider => { } }); var host = hostBuilder.Build(); await host.RunAsync();

IHostBuilder configuration with a function factory

The extension method UseServiceResolver has as input the HostBuilderContext instance in the lambda expression, and that reference can be used inside the factory function.

var hostBuilder = Host.CreateDefaultBuilder(args) // custom extension method to use for integration. .UseServiceResolver(context => new ServiceRegisterOptions<IServiceRegisterProvider> { // a factory used to create your service register provider OnCreating = collection => { return new CustomServiceRegisterProvider(new CustomServiceRegisterDescriptor()); }, // (optional) // an action used to prepare (if needed) your IServiceCollection. BeforeRegistering = collection => { // your IServiceCollection registrations or integrations }, // an action used to register your services. OnRegistering = provider => { // example: provider.Register<StringBuilder>(() => new StringBuilder("hello world..")); }, // (optional) // an action used to executes custom action at the end of all previous steps. AfterBuildingProvider = provider => { } }); var host = hostBuilder.Build(); await host.RunAsync();
