C＃摘要未出现在Web API的段落中

Question

/// <summary>

public IHttpActionResult Get(string timestamp)

上面是放置摘要的代码。即使我使用的是<para>，该描述仍在Web API帮助部分的连续行中显示，如屏幕截图所示。

我已经检查了生成的XML文件，看起来也不错，如下所示：

<member name="M:WebApplication.Controllers.MyDataController.Get(System.String)">
            <summary>
            <para>Here's how you could make a second paragraph in a description. <see cref="M:System.Console.WriteLine(System.String)"/> for information about output statements.</para>
            <para>Returns the status of system in JSON format</para>
            <para>URI format to call this GET API</para>
            <para>Note that the Timestamp MUST be in the format yyyyMMddHHmmssfff</para>
            </summary>
            <param name="timestamp"></param>
            <returns></returns>
        </member>
