Web Api 2路由无法使用guid作为参数进行解析

Question

我在下面定义了一个类，并使用以下URL命中

此网址有效： http://rooturl.com/website/api/v1/queuedNotifications

此网址没有 http://rooturl.com/website/api/v1/queuedNotifications/4b2a366b-e349-468d-99e6-b60918dc79f9

此网址没有 http://rooturl.com/website/api/v1/notifications/4b2a366b-e349-468d-99e6-b60918dc79f9

它没有将URL的末尾的GUID识别为GET的参数。谁能告诉我我可能做错了什么？我将约束放在GUID的路由前缀上，参数名称匹配......不确定是什么。

我的网址无法正常使用404.0错误

<legend>Error Summary</legend>
<h2>HTTP Error 404.0 - Not Found</h2>
