IIS 10.0 详细错误 - [httpDelete] [httpPut] 的 404.0

我正在尝试在 ASP.NET MVC 中创建一个 api。不幸的是，我有两个 HTTP 请求的问题：DELETE 和 PUT

    [ActionName("Index")]
    [HttpGet]
    public String Index()
    {
        return "get";
    }

    [ActionName("Index")]
    [HttpPost]
    public String IndexPost()
    {
        return "create";
    }


    [ActionName("Index")]
    [HttpPut]
    public String IndexPut()
    {
        return "update";
    }
    [ActionName("Index")]
    [HttpDelete]
    public String IndexDelete()
    {
        return "delete";
    }

当我尝试发送 DELETE 或 PUT 时，GET 和 POST 请求工作得很好，然后浏览器返回 IIS 10.0 详细错误 - 404.0 - 未找到。

<system.webServer>
<modules>
  <remove name="WebDAVModule"/>
</modules>
<handlers>
  <remove name="WebDAV" />
  <remove name="ExtensionlessUrl-Integrated-4.0" />
  <add name="ExtensionlessUrl-Integrated-4.0" path="*." verb="GET,HEAD,POST,DEBUG,DELETE,PUT" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />

Web.config 中的此更改解决了我的问题
