How can dependency injection be used in AI services within ASP.NET Core?

Dependency Injection in ASP.NET Core is used to Automate and Manage the AI services without creating it manually.  The main purpose of Dependency Injection is to make Application clean, modular, reusable and maintainable.  Instead of directly creating objects we use Dependency Injection (DI) In AI based application chatbot services, prediction services, recommendation system and API Integration.

suppose an AI chatbot service uses Open AI API, normally if we create a new AI Service every time then the code will become tightly coupled.  Dependency Injection Solves this problem by using Automatically service provide and whatever needed. 

DI must follow several steps :
Step 1 : Create AI Service

public class AIService
{
   public string GetResponse(string message)
   {
       return "AI Response for: " + message;
   }
}

step 2 : Register Service in Program.cs

builder.Services.AddScoped<AIService>();

step 3: Inject service into controller

using Microsoft.AspNetCore.Mvc;
public class ChatController : Controller
{
   private readonly AIService _aiService;
   public ChatController(AIService aiService)
   {
       _aiService = aiService;
   }
   public IActionResult Index()
   {
       var response = _aiService.GetResponse("Hello");
       return Content(response);
   }
}

DI ensures:

• Loose Coupling
• Easy Maintenance 
• Reusability 
• Better Testing
