.net 6 module/feature structure

Question

Hi, I'm not sure if it's the right place for my struggle.

I'm looking for a documentation page, I think it's a Microsoft documentation, it's about .Net 6 web API modular/feature project structure.
I couldn't find the page and I didn't bookmark it. I searched my browser history and still nothing.
The only thing I remember is a little block of code:

Modules  
   User.cs  
      User.requestDTO.cs  
      User.respondDTO.cs  

"requestDTO" and "responseDTO" are not the exact naming used in that tutorial.

We can find a similar tutorial here but I liked what I saw on that page I can't find.
I know it's vague and not really clear but if someone remembers having seen it can you please point it out.

Hi @Sinan ,
We had a hard time finding exactly the documentation you mentioned.
From your description, you should want to use AutoMapper. You can check the documentation to see if it's what you want.
https://docs.automapper.org/en/stable/Getting-started.html
https://github.com/thiago-vivas/Articles/tree/master/AutoMapperWebAPI

Here are some relevant links I found, hope you have what you are looking for.
https://learn.microsoft.com/en-us/aspnet/web-api/overview/data/using-web-api-with-entity-framework/part-5
https://learn.microsoft.com/en-us/aspnet/core/tutorials/first-web-api?view=aspnetcore-7.0&tabs=visual-studio#prevent-over-posting

I don't believe the modules belong in the web application project. the web application should just be the ui components, all modules should be in their own projects. DTO's should never be referenced in a UI projects. The data module should supply proper abstraction of the entities.

/WebApplication  
   appsetting.json  
   program.cs  
   webaapplication.csproj  
   /controllers  
   /views  
   /models  
  
/Modules  
  /Module1  
      module1.cs  
      module1.csproj  
      /models  
      /adapters  
  /Module2  
      module2.cs  
      module2.csproj  
      /models  
      /adapters  
  

note: models should be POCO objects, not DTO's. DTO's if used, belong in the data layer.
