unable to setup swagger UI in WEB API .net framework project - asp.net-web-api

Question

i have SwaggerConfig Setup like this
public class SwaggerConfig
{
public static void Register()
{
var thisAssembly = typeof(SwaggerConfig).Assembly;
GlobalConfiguration.Configuration
.EnableSwagger(c =>
{
c.SingleApiVersion("v1", "My.API");
})
.EnableSwaggerUi(c =>
{
});
}
}
and WebApiConfig setup like this
public static class WebApiConfig
{
/// <summary>
/// Register Method for Configuration Settings.
/// </summary>
/// <returns>Returns a HttpConfiguration which is a complex object which represents a configuration of HttpServer.
/// </returns>
public static HttpConfiguration Register()
{
var config = new HttpConfiguration();
// Web API routes
config.MapHttpAttributeRoutes();
config.MessageHandlers.Add(new CancelledTaskBugWorkaroundMessageHandler());
// SetupOData(config);
// require authentication for all controllers
config.Filters.Add(new AuthorizeAttribute());
config.Filters.Add(new HostAuthenticationAttribute("Bearer"));
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
config.Routes.MapHttpRoute(
name: "GetPagedData",
routeTemplate: "{controller}/{pageNumber}/{pageSize}"
);
// Web API configuration and services
config.EnableCors();
// pulling out the XML for now -teg
config.Formatters.XmlFormatter.SupportedMediaTypes.Clear();
config.Formatters.JsonFormatter.SerializerSettings.ReferenceLoopHandling =
Newtonsoft.Json.ReferenceLoopHandling.Ignore;
config.Formatters.JsonFormatter.SupportedMediaTypes.Add(
new MediaTypeHeaderValue("application/json-patch+json"));
config.Formatters.JsonFormatter.SupportedMediaTypes.Add(
new MediaTypeHeaderValue("text/html"));
var logger = new LoggerConfiguration()
.ReadFrom.AppSettings()
.CreateLogger();
config.Services.Add(typeof(IExceptionLogger), new MedefisExceptionLogger(logger));
config.Filters.Add(new CommonExceptionFilterAttribute());
var json = config.Formatters.JsonFormatter;
json.SerializerSettings.Formatting = Newtonsoft.Json.Formatting.Indented;
json.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver();
config.Services.Replace(typeof(IDocumentationProvider),
new XmlCommentDocumentationProvider(HttpContext.Current.Server.MapPath("~/App_Data/Medefis.API.XML")));
return config;
}
}
in the Startup.cs i am calling SwaggerConfig.Register() and few lines later i am also calling WebApiConfig.Register()
public class Startup
{
/// <summary>
/// Configuration for IAppBuilder on MedefisAPIUri
/// </summary>
/// <param name="app"></param>
public void Configuration(IAppBuilder app)
{
var builder = new ContainerBuilder();
SwaggerConfig.Register();
var logger = new LoggerConfiguration()
.ReadFrom.AppSettings()
.CreateLogger();
logger.Information("Api Startup");
AutoMapperConfiguration.Configure();
//CreateFoldersOnFileSystem();
app.UseCors(CorsOptions.AllowAll);
JwtSecurityTokenHandler.InboundClaimTypeMap = new Dictionary<string, string>();
AntiForgeryConfig.UniqueClaimTypeIdentifier = IdentityServer3.Core.Constants.ClaimTypes.Subject;
if (ConfigurationManager.AppSettings["UseIdentityServer"] == "True")
{
app.UseIdentityServerBearerTokenAuthentication(
new IdentityServerBearerTokenAuthenticationOptions
{
Authority = MedefisConstants.MedefisSTSConfig,
RequiredScopes = new[] { MedefisConstants.Scopes.api },
ClientId = MedefisConstants.Scopes.api,
ClientSecret = MedefisConstants.Secrets.InternalAPIClientSecret
}
);
}

//Setup
var config = WebApiConfig.Register();
builder.RegisterWebApiFilterProvider(config);
builder.RegisterInstance(config).As<HttpConfiguration>().SingleInstance().PropertiesAutowired();
var container = builder.Build();
config.EnableDependencyInjection();
config.DependencyResolver = new AutofacWebApiDependencyResolver(container);
app.Use(typeof(WebApiAuthUserMiddleware));
app.UseAutofacMiddleware(container);
app.UseAutofacWebApi(config);
app.UseWebApi(config);
app.UseCookieAuthentication(new CookieAuthenticationOptions
{
AuthenticationType = "Cookies"
});
config.EnsureInitialized();
}
}
the problem is that when i call http://localhost:xxxx/swagger it redirects to /swagger/ui/index but i get the error
No type was found that matches the controller named 'swagger'
please not the i am using Swashbuckle.Net45 version 5.2.1
Update
after prefixing the paths with "api/" in routeTemplate: "api/{controller}/{id}""
i was able to load the UI but none of paths and definitions are empty.

Answer 1

Solution was not to use SwaggerConfig.Register() separately instead do this configuration inside WebApiConfig.
