Question

自动解析.Net Core框架并没有在DryIoC中找到我的注册。

这使用新的.Net Core 2框架，DryIoC 2.10.7和DryIoc.Microsoft.DependencyInjection 1.2.2。我无法更新到DryIoC 2.11.7，因为DryIoc.Microsoft.DependencyInjection没有获取最新版本。在2.11.7安装之后我确实尝试重新安装后者但是没有用（模糊引用）。

这是我的启动代码：

public void ConfigureServices(IServiceCollection services)
{
    services.AddMvc()
            .AddControllersAsServices();

    var container = new Container(rules => rules.With(propertiesAndFields: PropertiesAndFields.Auto))
                   .WithDependencyInjectionAdapter(services);
    container.ConfigureServiceProvider<CompositionRoot>();
}

以下是我的注册码：

public CompositionRoot(IRegistrator registrator, IContainer container)
{
        //System Clock
        registrator.Register<IClock, ConcreteClock>(Reuse.Singleton, null, null, IfAlreadyRegistered.Keep);
        container.RegisterInstance<ISystemConfiguration>(new Configuration(container.Resolve<IClock>()), Reuse.Singleton, IfAlreadyRegistered.Keep);

        //Logging
        container.RegisterInstance<ILogging>(CreateLogger(container.Resolve<ISystemConfiguration>()), Reuse.Singleton, IfAlreadyRegistered.Keep);
}

最后是控制器：

public class AdminController : Controller
{
    private readonly ILogging _log;
    private readonly IClock _clock;
    public AdminController(ILogging log,
                           IClock clock)
    {
        _log = log;
        _clock = clock;
    }
}

以下是例外：

谢谢！

使用自定义DI框架时，您需要更新ConfigureServices以返回自定义IServiceProvider。

public IServiceProvider ConfigureServices(IServiceCollection services) {
    services.AddMvc()
            .AddControllersAsServices();

    var container = new Container(rules => rules.With(propertiesAndFields: PropertiesAndFields.Auto))
                   .WithDependencyInjectionAdapter(services);
    var provider = container.ConfigureServiceProvider<CompositionRoot>();
    return provider
}

在运行时，您的提供程序将用于解析类型并注入依赖项。
