c# - Swashbuckle swagger RootUrl/swagger/docs にアクセスしても出力が得られない

Question

Web API 2 プロジェクトがあります。これは、owin を使用して自己ホストされるように構成されています。global.asax ファイルはありません。Web API のヘルプ ページが必要で、swaschbuckle を使用しています。しかし、rooturl/swagger/docs には出力がありません。

こちらの「 https://github.com/domaindrivendev/Swashbuckle/issues/196 」の指示に従いましたが、まだ機能していません。以下は私の設定コードです

public void Configuration(IAppBuilder app)
{
    // Configure DI
    container = BuildDI();

    // Create the configuration. OWIN Should create a new httpconfiguration.
    // GlobalConfiguration can't be used.
    HttpConfiguration = new HttpConfiguration();

    HttpConfiguration.Formatters.XmlFormatter.UseXmlSerializer = true;
    HttpConfiguration.MapHttpAttributeRoutes();
    HttpConfiguration.DependencyResolver = new AutofacWebApiDependencyResolver(container);

    // Set ServicePointManager properties.
    ServicePointManager.ServerCertificateValidationCallback = ((sender, cert, chain, sslPolicyErrors) => true);

    // 10 concurrent connections can be made on the service point.
    ServicePointManager.DefaultConnectionLimit = 10;

    // After the idle time expires, the ServicePoint object is eligible for 
    // garbage collection and cannot be used by the ServicePointManager object.
    ServicePointManager.MaxServicePointIdleTime = 30000; // 30 Seconds.

    app.UseSerilogRequestContext("RequestId");

    // Middleware is injected form DI.
    app.UseAutofacMiddleware(container);

    app.UseAutofacWebApi(HttpConfiguration);

    //Enable swashbuckle
    SwaggerConfig.Register(HttpConfiguration);

    // Webapi middleware. Do it at the end.
    app.UseWebApi(HttpConfiguration);

    // Register callback to dispose container.
    RegisterShutdownCallback(app, container);
}

public class SwaggerConfig
{
    public static void Register(HttpConfiguration config)
    {
        config.EnableSwagger(c =>
        {
            c.RootUrl(rurl => ConfigurationManager.AppSettings["hostUrl"].ToString());
            c.IncludeXmlComments(GetXmlCommentsFileLocation());
            c.SingleApiVersion("v1", "Isone");
        })
        .EnableSwaggerUi(c =>
        {
        });
    }

    private static string GetXmlCommentsFileLocation()
    {
        var baseDirectory = AppDomain.CurrentDomain.BaseDirectory + "\\bin";
        var commentsFileName = Assembly.GetExecutingAssembly().GetName().Name + ".XML";
        var commentsFileLocation = Path.Combine(baseDirectory, commentsFileName);

        return commentsFileLocation;
    }
}
