在控制器中使用Area时Url.Action（）的结果

Question

我正在阅读Microsoft文档，其中解释了有关Area用于路由https://docs.microsoft.com/en-us/aspnet/core/mvc/controllers/routing?view=aspnetcore-2.2#areas的用法。

有1个部分我无法理解。

app.UseMvc(routes =>
{
    routes.MapAreaRoute("duck_route", "Duck",
        "Manage/{controller}/{action}/{id?}");
    routes.MapRoute("default", "Manage/{controller=Home}/{action=Index}/{id?}");
});

控制器：

using Microsoft.AspNetCore.Mvc;

namespace MyApp.Namespace4
{
    [Area("Duck")]
    public class UsersController : Controller
    {
        public IActionResult GenerateURLInArea()
        {
            // Uses the 'ambient' value of area
            var url = Url.Action("Index", "Home"); 
            // returns /Manage
            return Content(url);
        }

        public IActionResult GenerateURLOutsideOfArea()
        {
            // Uses the empty value for area
            var url = Url.Action("Index", "Home", new { area = "" }); 
            // returns /Manage/Home/Index
            return Content(url);
        }
    }
}

为什么在GenerateURLInArea()动作中返回/Manage而在GenerateURLOutsideOfArea()返回/Manage/Home/Index呢？

@itminus突出显示，执行结果相反。 我也已经证实这是真的。

所以这应该是预期的行为

using Microsoft.AspNetCore.Mvc;

namespace MyApp.Namespace4
{
    [Area("Duck")]
    public class UsersController : Controller
    {
        public IActionResult GenerateURLInArea()
        {
            // Uses the 'ambient' value of area
            var url = Url.Action("Index", "Home"); 
            // returns /Manage/Home/Index
            return Content(url);
        }

        public IActionResult GenerateURLOutsideOfArea()
        {
            // Uses the empty value for area
            var url = Url.Action("Index", "Home", new { area = "" }); 
            // returns /Manage
            return Content(url);
        }
    }
}

这实际上更有意义：)

@itminus还为该修复程序发出了罚单https://github.com/aspnet/AspNetCore.Docs/issues/12221/
