我最近开始学习C#和ASP。我刚刚使用以下命令创建了一个ASP项目：

dotnet new webapi -n ProjectName

它有默认的示例项目。我可以构建并运行它，并使用以下URL从浏览器调用它：

http://localhost:5068/WeatherForecast

我不明白URL的***WeatherForecast***部分是如何确定的，因为我在任何地方都找不到该特定字符串。
这是控制器的内容：

using Microsoft.AspNetCore.Mvc;

namespace ProjectName.Controllers;

[ApiController]
[Route("[controller]")]
public class WeatherForecastController : ControllerBase
{
    private static readonly string[] Summaries = new[]
    {
        "Freezing", "Bracing", "Chilly", "Cool", "Mild", "Warm", "Balmy", "Hot", "Sweltering", "Scorching"
    };

    private readonly ILogger<WeatherForecastController> _logger;

    public WeatherForecastController(ILogger<WeatherForecastController> logger)
    {
        _logger = logger;
    }

    [HttpGet(Name = "GetWeatherForecast")]
    public IEnumerable<WeatherForecast> Get()
    {
        return Enumerable.Range(1, 5).Select(index => new WeatherForecast
        {
            Date = DateOnly.FromDateTime(DateTime.Now.AddDays(index)),
            TemperatureC = Random.Shared.Next(-20, 55),
            Summary = Summaries[Random.Shared.Next(Summaries.Length)]
        })
        .ToArray();
    }
}
