Hot Reload not effective on .NET Web API template

[PeterDraex]

Type: Bug

1. Run dotnet new webapi --use-controllers -o DebugHotReload to create a new project
2. Open your File -> Preferences, make sure hot reload is enabled
3. Open WeatherForecastController.cs, add new method:

       [HttpGet("TryThis")]
       public IActionResult TryThis()
       {
           return Ok("trythis");
       }

4. Start debugging using F5, use default C# debugging config.
5. Wait until the app starts. Open /WeatherForecast/TryThis in your browser
6. You should see trythis.
7. Change [HttpGet("TryThis")] to [HttpGet("TryThis2")] and rename the method to TryThis2.
8. Open /WeatherForecast/TryThis2 in your browser
9. EXPECTED is that you see trythis. ACTUAL result is a 404 error.

Posting this here, because it works as expected in Visual Studio 2022 preview.
