我希望了解如何在 Ubuntu 16.04 上的网页中呈现 ASP.NET 的脚本管理器，然后呈现 UpdatePanel。
以下 aspx 脚本代码在结合 Xamarin Studio 的 Windows 7 Microsoft Visual Studio 2013 上运行良好。
但是，当我在运行 apache2 和 xsp4 的 Firefox Web 浏览器中请求 URL 127.0.0.1:9000/Tutorial.aspx 时，遇到以下异常。
System.InvalidOperationException ID 为“UpdatePanel1”的控件需要页面上的 ScriptManager。 ScriptManager 必须出现在任何需要它的控件之前。
Description: HTTP 500.Error processing request.

<cc1:TabContainer id="TabControl" runat="server" activetabindex="0" AutoPostBack="True" OnActiveTabChanged="TabControl_ActiveTabChanged">
</cc1:TabContainer>
</ContentTemplate>
</asp:UpdatePanel>
请提出一个解决方案，使我能够避免上述异常。

[编辑 2016 年 6 月 29 日 7:06P.M] 今天晚上我发现我的问题的一个主要原因是我正在混合苹果和橙子。 “苹果”是 Microsoft 的 asp:ScriptManager，“橙子”是 Mono 的 asp:ScriptManager。有谁知道我为什么会收到此错误以及如何修复它？
任何帮助是极大的赞赏。
