Hello .net team, my writing is a suggestion to improve the .net documentation, the reason is that it does not explain the code well, and then one gets lost within the documentation, for example in the Api Controller section, they do not explain IActionResult , dependency injection, what each one is for, the data annotation, for example see the documentation of Angular, Laravel or React or Vue, it goes step by step explaining each section in a simple way is the way I see it, in question it is a suggestion of whether The .net documentation can be improved, I look forward to your response.
