ASP.NET AJAX无法在.NET 3.5的localhost上运行

时间：2015-06-19 18:37:41

标签： asp.net ajax

实时应用程序已经部署了一段时间并且运行正常。应用程序池是v2.0 Classic。它托管在Windows Server 2008 R2上。

我的本​​地环境是Windows 8.1。我在IIS Express中进行调试。我在浏览器开发人员工具中遇到以下错误：

  • 未捕获错误：ASP.NET Ajax客户端框架无法加载。
  • 未捕获的ReferenceError：未定义Sys

所有ScriptResource.axd GET请求都会导致404错误。有关修复.NET Ajax的任何想法吗？

顺便说一句，我已经完成了我之前看到的有关如何解决此问题的所有建议，尤其是处理程序。我有以下web.config。

我已经仔细检查了IIS Express的applicationhost.config中的AXD处理程序。看来我有.NET 2.0 AXD处理程序。 （但我在解释这些方面缺乏专业知识。）

由于站点配置为在.NET 2.0（或可能是3.5）中运行，您需要在bin中安装AJAX控件工具包DLL，因为它们可能安装在生产服务器上的GAC上，这就是它工作的原因那里。为了能够加载2.0 DLL，您需要将DLL安装到计算机上的GAC或将它们包含在bin目录中。 This answer应该有所帮助。

答案 1 :(得分：0)

固定。问题不在于我的web.config。事实上，我找不到任何文件或代码的任何问题。最终，我不得不重新创建项目并复制我的文件。具体来说，按顺序：

  1. 创建新的空ASP.NET项目。 （Visual Studio默认在4.5中执行此操作。）
  2. 将目标框架更改为3.5版。
  3. 从当前项目中复制代码文件。
  4. 在新项目的项目属性中，确保新项目的程序集名称和根名称空间与现有项目的名称相匹配。
  5. 在新项目中添加必要的引用。
  6. 以调试模式运行新项目，进行测试，确认一切正常。
  7. 将所有内容复制回来，覆盖旧项目，并注意以下事项：
    1. 无需覆盖旧解决方案（无论如何，在我的情况下）。
    2. 请务必覆盖旧的VS proj文件和bin文件夹。
    3. 我正在使用Git进行源代码管理，因此它会自动获取新的/不同的文件，并忽略其他文件。
  8. 就我而言，有两种可能性（我能想到）是问题的根源。我不知道哪个是真正的原因：
    1. 我失踪了/My Project/MyExtensions/MyWebExtension.vb。
    2. vsproj文件本身的东西。
