Fixing Controller

First we need to fix our controller, by removing redundant methods and replacing DateTime to Stopwatch.

using System.Diagnostics;
using Microsoft.AspNetCore.Mvc;

namespace ExampleProject;

[Route("[controller]")]
[ApiController]
public class MyController(IMyService service) : ControllerBase
{
    [HttpGet("/{name}")]
    public async Task<IActionResult> Get(string name)
    {
        var start = Stopwatch.GetTimestamp();
        var hello = await service.GetHello(name);
        return Ok($"{hello} It took {Stopwatch.GetElapsedTime(start)} to respond.");
    }
}

Attention!

When you using primary constructor, injectioning service imperceptibly becomes class field, so if Sigleton class depends on Scoped service that scoped service will life all time what's life a singleton.
