从 2010 升级后 VS 2013 HttpHandlers 不工作

Question

我最近将一个 ASP.NET 项目从 Visual Studio 2010 Professional 升级到 Visual Studio 2013 Community。

在项目中，我们定义了一些自定义处理程序来处理来自 Ajax 的请求或特殊用户请求（获取图像）。

问题是，现在我是运行ning 2013，当时我运行在调试中处理程序根本不起作用。当我尝试访问它们时，我得到一个 404 并且没有断点被触发。我知道 2010 使用开发服务器，而 2013 使用 IIS Express。

是 Web.Config 中的处理程序设置不正确还是 Web.config 本身设置不正确？

Web.Config

目前Web.Config

我没有转换设置

Answer 1

在经典的管道模式下，所有的处理程序都需要在配置 => system.web => httpHandlers 部分。
在管道的集成模式下，所有处理程序都需要在配置 => system.web服务器 => 处理程序部分中注册。在集成模式下不使用 httpHandlers 元素中定义的处理程序。
在您发布的 web.config 文件中，有一个名为 "httpHandlersadd" 的结束标记。我希望这是错字，如果不是那么你需要更正它。
