帮助页面上的WCF REST Uri不正确

Question

写了我的第一个WCF Rest服务并且进展顺利......但是我有一个小问题，有人可以帮忙吗？

当我转到我在本地电脑上的帮助页面时就是这样

  http://localhost/WcfRestService1/help

它显示以下内容，但URI错误，请注意URI为空或仅询问参数{id}

Uri     Method      Description
            GET     Service at http://localhost/WcfRestService1/
            POST    Service at http://localhost/WcfRestService1/
{id}        GET     Service at http://localhost/WcfRestService1/{ID}
            PUT     Service at http://localhost/WcfRestService1/{ID}
            DELETE  Service at http://localhost/WcfRestService1/{ID}

确实应该（参见下面的方法）

  Uri

  Tasks  Get .... 
  Users/{id}    Get ....

以下是我的方法，因此URI应显示正确的URI，请参阅我的属性UriTemplate

    [WebGet(UriTemplate = "Tasks")]
    public List<SampleItem> GetCollection()
    {
        // TODO: Replace the current implementation to return a collection of SampleItem instances
        return new List<SampleItem>() { new SampleItem() { Id = 1, StringValue = "Hello" } };
    }

    [WebGet(UriTemplate = "Users/{id}")]
    public SampleItem Get(string id)
    {
        // TODO: Return the instance of SampleItem with the given id
        //throw new NotImplementedException();
        return new SampleItem() {Id = 1, StringValue = "Hello"};
    }
