+## 트러블슈팅
+
+런타임에서, 아래와같은 Exception 발생시, `builder.Services.AddEndpointsApiExplorer();` 구문 추가가 도움이 될수있습니다.
+```csharp
+System.AggregateException: Some services are not able to be constructed (Error while validating the service descriptor 'ServiceType: Swashbuckle.AspNetCore.SwaggerGen.SwaggerGenerator Lifetime: Transient ImplementationType: Swashbuckle.AspNetCore.SwaggerGen.SwaggerGenerator': No constructor for type 'Swashbuckle.AspNetCore.SwaggerGen.SwaggerGenerator' can be instantiated using services from the service container and default values.)
+```
+
+
+참고  
+MagicOnion 에서 사용된 Swashbuckle.AspNetCore.Swagger 의 사용법이 기록된 MSDN 입니다.

+
+```csharp
+builder.Services.AddEndpointsApiExplorer();
