System.Web.UI.ScriptManager“在未被引用的程序集中定义。但它是在组装？ [英] System.Web.UI.ScriptManager' is defined in an assembly that is not referenced. But it is in the assembly?

问题描述

我只是说Ajax来我的网站，我使用toolkitscript经理，当我去构建它它产生的错误。

I just added Ajax to my website and i'm using toolkitscript manager, when i go to build it it produces the error.

类型System.Web.UI.ScriptManager'中未被引用的组件被定义。您必须添加一个引用程序集，版本= 4.0.0.0，文化=中性公钥= 31bf3856ad364e35

The type 'System.Web.UI.ScriptManager' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35

这是我整个的web.config，我已经看到系统>网络>扩展引用，还有什么可能是这个问题？

here is my entire web.config, I already see System>web>extensions referenced, what else could be the issue?

这是它在我的aspx如何。

This is how it is in my aspx.

<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="cc1" %>

<cc1:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server">
</cc1:ToolkitScriptManager>`

修改

下面是解决方案：

＆LT;编译调试=真正的targetFramework =4.0＆GT;

据失踪targetFramework =4.0

It was missing targetFramework = "4.0"

推荐答案

地址：targetFramework =4.0到编辑标签

Add: targetFramework="4.0" to the compilation tag.

<compilation debug="true" **targetFramework="4.0"**>
