我正在尝试按照以下说明将我的记录器作为 .Net Framework 4.7.2 web api 项目中的依赖项注入：

这对 MVC Web 应用程序很有用，但在 webapi 项目上失败，并出现“无参数构造函数丢失”错误。

如何仅使用默认程序集成功注入：Microsoft.Extensions.DependencyInjection in framework？

public class Startup
{
    public void Configuration(IAppBuilder app)
    {

        var services = new ServiceCollection();
        ConfigureServices(services);
        var resolver = new DefaultDependencyResolver(services.BuildServiceProvider());
        DependencyResolver.SetResolver(resolver);
    }

    public void ConfigureServices(IServiceCollection services)
    {
        services.AddControllersAsServices(typeof(Startup).Assembly.GetExportedTypes()
            .Where(t => !t.IsAbstract && !t.IsGenericTypeDefinition)
            .Where(t => typeof(IController).IsAssignableFrom(t)
                        || t.Name.EndsWith("Controller", StringComparison.OrdinalIgnoreCase)));
        services.AddSingleton<IMyInterface , MyClass>();
    }
}
public class DefaultDependencyResolver : IDependencyResolver
{
    protected IServiceProvider serviceProvider;

    public DefaultDependencyResolver(IServiceProvider serviceProvider)
    {
        this.serviceProvider = serviceProvider;
    }

    public …
