Hi there, I'm İlker 👋

I'm a Husband, Father and Developer

• 🔭 I’m currently working on a ASP.Net Core 6 Clean Architecture Solution Template!

• 🌱 I can put learning first among my interests. Because of my curiosity, I add new research topics before I finish. Therefore the list goes on and on.

  • 📡 I am eager to try dapr in production level.
    • 🌕 Service to Service Invocation (HTTP/gRPC)
    • 🌖 State Management (RDBMS / NOSQL)
    • 🌗 Publish and Subscribe(Azure Service Bus, AWS SQS/SNS - Kinesis, Apache Kafka, RabbitMQ, Redis)
    • 🌘 Input and Output Bindings triggering application and invoking external resources
    • 🌑 Actors : Virtual Actor Pattern implementation for concurrency and better scalability
    • 🌒 Observability distributed tracing using Zipkin API and Open Telemetry Collector
    • 🌓 Secrets Management Azure Key Vault/AWS Secret Manager or Dapr secrets API
  • 🏆 Scalable distributed applications, Event Sourcing , CQRS, Event Driven Architecture
  • ⚽ Kali Linux (I want to learn cyber security and try hack myself)
  • 🎯 Networking (Cisco CCNA maybe after CCNP I dont care the certificates, i just want to learn. 😃)

Duplication in mediator handlers

How to use duplicate code in handler?
Does the static method take up a lot of memory when a lot of data is exchanged?
Base on @ShreyasJejurkar
It's not recommended to send another request from request handlers. The purpose of using MeditR is just to convert HTTP requests to our application-specific requests and send them into the application layer without letting the controller knows about it or any other presentation layer.

What is the best solution to not occupy a lot of memory?
Static method or utility class or service or Application services or abstraction layers or domain layer?

What is the code you suggest?

How to have Navigation in User Model and Other Entities

Since Our Identity models are in the Infrastructure Layer and other Entities are in the Domain Layer, I was wonder to know how can we have navigation between an Entity and User Model?

For instance, I have two models, User and Content, Each user has 0 or many contents so there should be a List in User Model, and in Content there should be a foreign Key of User

Public class User{

 Public List<Content> Contents{get;set;}

}

Occasionally receive 401 (Unauthorized)

I occasionally receive the error 401 (Unauthorized) after login. I am then required to restart the application pool and it will work fine again for a few days or sometimes weeks.

Not a big application or complicated app by any means (< 10 users and not much more complicated than the todo sample code). Memory usage is below 200 MB.

I am fairly new to Web API, Angular, and IdentiyServer programming so I assume the problem is something I am doing wrong.

Any ideas on where to look are highly appreciated.

Microservice Architecture Service Meshes, API Gateways, and Message Queues

API Gateways

• Ocelot
• Tyk
• Kong
• AWS API Gateway, Azure Api Management or Google Cloud Endpoints

Service Meshes

• Istio --- microservice example
• Linkerd
• Consul Connect
• Kuma

Message Queues

• RabbitMQ
• Apache/Kafka
• Azure Service Bus
• AWS SQS
• Google Cloud Pub/Sub

Technologies

• Dapr
  • Linkerd with Dapr
  • Istio with Dapr
  • Redis pub/sub
• dotnet/orleans
• Knative
• akka

I am really interested in using Dapr. We can use service mesh like Linkerd and message queues like RabbitMQ with Dapr.

We can use service meshes to manage the network between microservices. If we need message queues, it can be used with Dapr bindings RabbitMQ.

I'm waiting for suggestions. Thank you for your attention.

DenyAnonymousAuthorizationRequirement: Requires an authenticated user

This probably isn't a bug, just me not understanding .NET 5 + AspNetCore libraries, so I didn't click Bug Report just yet.

I followed the steps on the README but when trying it out through Swagger (the URL that pops up) it doesn't seem to authenticate. I tried using Super_Secret_Key as the token to authorize but got this...

and in console, the message that's in the subject of this issue.

Sorry, I'm still learning the AspNetCore libraries. Thanks for being patient with me. I have a lot of webapp experience and .NET Framework but haven't made my way into the .NET 5 API world until now.

I did get it working if I use Client.WorkerService... is it just the Swagger script that isn't working?

I tried through Postman with the same response. How would one authenticate through an API key?

Can you guide me to the right spot to add authorized tokens, or if it's just one token like Super_Secret_Key let me know what I'm doing wrong.

Thank you very much!

hi, This is a code generation plug-in for CleanArchitecture

maybe you need it. Can greatly increase your productivity.

Authorize with Policy show 'The type or namespace could not be found'

Hi, I facing the issues with Authorize attribute when using policy

Since in your code using custom authorize class, so I unable to implement policy here.

If using Microsoft.AspNetCore.Authorization.AuthorizeAttribute, then the authorization is not working.

Example

//Need use this, or else show an error 'The type or namespace could not be found'
using AuthorizeAttribute = Microsoft.AspNetCore.Authorization.AuthorizeAttribute;


[HttpPost]
[Route("uom")]
[Authorize(Policy = "user.read.policy")] // Is not working
[ProducesResponseType(typeof(ServiceResult<ItemUomDto>), (int)HttpStatusCode.OK)]
public async Task<ActionResult<ServiceResult<ItemUomDto>>> Create([FromBody] CreateItemUomCommand command)
{
     return Ok(await Mediator.Send(command));
}

Any idea how we can solve?

Return Task<ServiceResult> without <T>

Based on this code

 public async Task<ServiceResult<CityDto>> Handle(UpdateCityCommand request, CancellationToken cancellationToken)
        {
            var entity = await _context.Cities.FindAsync(request.Id);

            if (entity == null)
            {
                throw new NotFoundException(nameof(City), request.Id);
            }
            if (!string.IsNullOrEmpty(request.Name))
                entity.Name = request.Name;
            entity.Active = request.Active;

            await _context.SaveChangesAsync(cancellationToken);

            return ServiceResult.Success(_mapper.Map<CityDto>(entity));
        }

Any I idea how I can return ServiceResult without Dto? I just want to return public async Task<ServiceResult> Handle(UpdateCityCommand request, CancellationToken cancellationToken)

In some case, I just want to tell success only

Thanks in advance.

Clean architecture with EF Core DB First approach

Hi,

I am implementing clean architecture using the existing database, with scaffolding command I have generated the POCO entities in the Infrastructure layer and as well as manually created the entities in the domain layer to map them later.

in the Application layer, I have the generic interface repository with a few standard operations.

public interface IRepository<T> where T : class
 {
     Task<IReadOnlyList<T>> GetAllAsync();
     Task<T> GetByIdAsync(int id);
     Task<T> AddAsync(T entity);
     Task UpdateAsync(T entity);
     Task DeleteAsync(T entity);
 }

As per the principles of Clean-Architecture, I am implementing it in the Infrastructure layer.

public class Repository<T> : IRepository<T> where T : class
    {

        protected readonly MyDBContext _MyDBContext;
        public Repository( MyDBContext mydbContext)
        {
            _MyDBContext= mydbContext;
        }
        public async Task<T> AddAsync(T entity)
        {
            await _MyDBContext.Set<T>().AddAsync(entity);
            await _MyDBContext.SaveChangesAsync();
            return entity;
        }

As per the template, I am using a Mediator pattern with CQRS, when I try to save the user from the API layer I will end up with the below exception.

System.InvalidOperationException: Cannot create a DbSet for 'ABC.Domain.Entities.User' because this type is not included in the model for the context. However, the model contains an entity type with the same name in a different namespace: 'ABC.Infrastructure.Models.User'.

It will be resolved if I can able to map the domain entity to the infrastructure entity in the above Repository implementation.
In the above implementation, the T is the ABC.Domain.Entities.User, not the ABC.Infrastructure.Models.User. I can't pass the ABC.Infrastructure.Models.User from the Application layer ( because I can't add a reference to the Infrastructure layer in Application layer) due to the rule Clean Architecture all dependencies flow inwards and Core has no dependency on any other layer.

Please help me to map the incoming domain entity with the infrastructure entity in the above repository implementation so that I can use these general methods for other entity operations as well.

@iayti .. Please do the needful.
