Tauntalizing vb.net error: XML literals and XML axis properties are not available, as a required reference was not provided

Question

所以我在我的遗留 vb.net 应用程序中添加了一些这样的代码（刚从框架 2.0 升级到 4.0 - 所以缺少默认引用）：

    eag.stAgentXML = _
       <Agent>
         <Number><%= (CaseRoot.AgentForCase.State.PadLeft(4, "0"c) & " " & _
                   CaseRoot.AgentForCase.Number.PadLeft(4, "0"c) & "-" & _
                   CaseRoot.AgentForCase.Rank) %></Number>
         <Name><%= CaseRoot.AgentForCase.LastName & ", " & CaseRoot.AgentForCase.FirstName %></Name>
       </Agent>.Value

它给了我这个非常有用的信息：

XML literals and XML axis properties are not available, as a required reference was not provided

在 vb.net 团队中，我可以向谁大喊大叫，因为他们没有做到最后一毫米，实际上 告诉我 要包括哪个参考？

他们为什么不直接告诉我他们的真实感受，并阅读错误消息，"Nice try but this code is wrong. good luck."

哦 - 我不介意知道如何让它真正起作用。
