Making changes to our REST API

In a previous section, we launched our REST API with the dotnet watch run command. The watch portion of this command instructs the dotnet command to watch our project for changes, and autoreload the application with those changes applied. Let's see this in action!

First, we'll open our App folder in Visual Studio Code. Once it's open, navigate to the App.WebApi\Controllers\WeatherForecastController.cs file and find where it's generating the weather forecasts:

[HttpGet]

        .Select(index => new WeatherForecast
        {
            Date = DateTime.Now.AddDays(index),
