Class StartupFactory<TStartup>

Namespace: Codebelt.Bootstrapper

Assembly: Codebelt.Bootstrapper.dll

The default implementation of IStartupFactory<TStartup>.

public class StartupFactory<TStartup> : IStartupFactory<TStartup> where TStartup : StartupRoot

Type Parameters

TStartup

Inheritance: object

StartupFactory<TStartup>

Implements: IStartupFactory<TStartup>

Examples

The following example shows how StartupFactory<TStartup> activates a StartupRoot partner from the host's IServiceCollection, configuration, and environment, then surfaces it through the IStartupFactory<TStartup>.Instance property. The factory is what UseBootstrapperStartup<TStartup> registers, so consumer code resolves the singleton instead of constructing the startup directly.

using Codebelt.Bootstrapper;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;

namespace StartupFactoryDemo;

public class MyStartup : StartupRoot
{
    public MyStartup(IConfiguration configuration, IHostEnvironment environment) : base(configuration, environment)
    {
    }

    public override void ConfigureServices(IServiceCollection services)
    {
    }
}

public static class Program
{
    public static void Main()
    {
        using var host = Host.CreateDefaultBuilder()
            .UseBootstrapperStartup<MyStartup>()
            .Build();

        var factory = (StartupFactory<MyStartup>)host.Services.GetRequiredService<IStartupFactory<MyStartup>>();
        var startup = factory.Instance;
    }
}
