asp.net-web-api - 使用 OWIN 自托管 WebAPI 时出现 EntryPointNotFoundException

Question

我正在尝试通过以下链接使用 OWIN 自托管 Web API

http://www.asp.net/web-api/overview/hosting-aspnet-web-api/use-owin-to-self-host-web-api

但是，在执行下面这行的过程中

using (WebApp.Start<SelfHostStartup>(url: baseAddress))

我收到EntryPointNotFoundException，因为在程序集中找不到 MyNamespace.SelfHostStartup。

任何帮助，将不胜感激。

谢谢你。

public class SelfHostStartup
{
    // This code configures Web API. The Startup class is specified as a type
    // parameter in the WebApp.Start method.
    public void Configuration(IAppBuilder appBuilder)
    {
        // Configure Web API for self-host. 
        var config = new HttpConfiguration();

        // Loads external library's (that contain the web api controllers) into the web api self host system
        var assemblyResolver = new SelfHostAssemblyResolver();
        config.Services.Replace(typeof(IAssembliesResolver), assemblyResolver);

        // Creates the IoC Container & mounts to Web API
        config.DependencyResolver =
            new AutofacWebApiDependencyResolver(Framework.Infastructure.Dependency.AutofacContainer.Container);

        config.Services.Add(typeof(IExceptionLogger), new MyNamespace.ApiExceptionLogger(Framework.Infastructure.Dependency.AutofacContainer.Resolve<ILogger>()));
        // Configures Web API Controller Routing
        RouteConfig(config);

        config.EnsureInitialized();
        // Tells OWIN self host to use this configuration
        appBuilder.UseWebApi(config);
    }

    /// <summary>

        config.MapHttpAttributeRoutes();
        config.Routes.MapHttpRoute(

            );
    }
