ServiceResolver.GenericHost.SimpleInjector 3.3.1

About this library

ServiceResolver.GenericHost.SimpleInjector is a library for .NET generic host, which uses ServiceResolver.Ioc.SimpleInjector library.

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

IHostBuilder configuration

var hostBuilder = Host.CreateDefaultBuilder(args)
    // custom extension method to use for integration.
    .UseServiceResolver(new SimpleInjectorOptions
    {
        // (optional)
        BeforeRegistering = collection =>
        {
            // your IServiceCollection registrations or integrations if needed
        },
        // an action uses to register your services.
        OnRegistering = provider =>
        {
            // example:
            provider.Register<StringBuilder>(() => new StringBuilder("hello world.."));
        },
        // (optional)
        AfterBuildingProvider = provider =>
        {
            // an action uses to executes custom action at the end of all previous steps.
            provider.Verify();
        }
    });

var host = hostBuilder.Build();

await host.RunAsync();

IHostBuilder configuration with a function factory

var hostBuilder = Host.CreateDefaultBuilder(args)
    // custom extension method to use for integration.
    .UseServiceResolver(context => new SimpleInjectorOptions
    {
        // (optional)
        BeforeRegistering = collection =>
        {
            // your IServiceCollection registrations or integrations if needed
        },
        // an action uses to register your services.
        OnRegistering = provider =>
        {
            // example:
            provider.Register<StringBuilder>(() => new StringBuilder("hello world.."));
        },
        // (optional)
        AfterBuildingProvider = provider =>
        {
            // an action uses to executes custom action at the end of all previous steps.
            provider.Verify();
        }
    });

var host = hostBuilder.Build();

await host.RunAsync();

Configuration for AspNet applications (NET6 or higher)

For the given examples, you need to install the ServiceResolver.GenericHost.AspNetCore nuget package.

WebApplicationBuilder configuration

var builder = WebApplication.CreateBuilder(args);

builder.Host
    .UseServiceResolver(new SimpleInjectorOptions
    {
        //ConstructorResolutionType = ResolutionType.Hybrid,
        IgnoreMissingRegistrations = true,
        BeforeRegistering = collection =>
        {
            collection.AddControllers();
        },
        OnRegistering = serviceRegister =>
        {
            // minimal configuration for aspnet
            serviceRegister
                .AddAspNetCore()
                .AddControllerActivation()
                ;
        },
        AfterBuildingProvider = provider =>
        {
            provider.Verify();
        }
    })
    ;

var app = builder.Build();

// Configure the HTTP request pipeline.
app.UseAuthorization();
app.MapControllers();
await app.RunAsync();

WebApplicationBuilder configuration with a function factory

var builder = WebApplication.CreateBuilder(args);

builder.Host
    .UseServiceResolver(context => new SimpleInjectorOptions
    {
        //ConstructorResolutionType = ResolutionType.Hybrid,
        IgnoreMissingRegistrations = true,
        BeforeRegistering = collection =>
        {
            collection.AddControllers();
        },
        OnRegistering = serviceRegister =>
        {
            // minimal configuration for aspnet
            serviceRegister
                .AddAspNetCore()
                .AddControllerActivation()
                ;
        },
        AfterBuildingProvider = provider =>
        {
            provider.Verify();
        }
    })
    ;

var app = builder.Build();

// Configure the HTTP request pipeline.
app.UseAuthorization();
app.MapControllers();
await app.RunAsync();
