在 VS 中调试时，在 VS 中启动调试时会引发错误。

错误如下：

当我创建一个使用“p4dn.dll”的 C# 项目时，没有遇到这个错误。

这是我的第一个 ASP 项目，我还阅读了类似的问题，例如“http://stackoverflow.com/questions/41449/i-get-a-an-attempt-was-made-to-load-a-program-with -an-incorrect-format-error-o”和“http://stackoverflow.com/questions/1648213/could-not-load-file-or-assembly-xxx-or-one-of-its-dependencies-an -尝试-是”。他们无法解决我的问题。

我怎么解决这个问题？

现在有一个菜单选项可以运行 64 位版本的 IIS Express。从 Visual Studio 菜单中选择工具 -> 选项... -> 项目和解决方案 -> Web 项目

单击“为网站和项目使用 64 位版本的 IIS Express”按钮

我在尝试使用 IIS Express 8.0 运行（调试）一个 64 位 MVC 站点时遇到了同样的错误消息。我确认我所有的项目都针对 x64 平台。

出现此问题的原因是 Visual Studio 运行 32 位版本的 IIS Express。我可以让它工作的唯一方法是通过手动执行以下命令来运行 64 位 IIS Express。

"C:\Program Files\IIS Express\iisexpress.exe"  /config:"U:\IISExpress\config\applicationhost.config"  /site:"Imaging.Web" /apppool:"Clr4IntegratedAppPool"

然后在您的 Visual Studio Web 项目中转到“属性”，选择“使用自定义 Web 服务器”，然后输入您网站的 url。

为了调试，请转到调试 > 附加到进程.. 然后选择您正在运行的 IIS Express 实例。

Visual Studio 团队确实应该在项目属性中将此作为选项。

-为您的网站创建一个新的 IIS 池 -为此池启用 32 位

使用 C# 在 Asp.Net 上进行本地化项目

项目在本地机器上运行良好。在 IIS 和 Web 服务器上上传后，它没有工作并且无法加载文件或程序集“App_global.asax”或其依赖项之一。此程序集由比当前加载的运行时更新的运行时构建，无法加载。来了。

在此处输入图像描述

在 IIS 上将应用程序池从 v2.0 更改为 V4.0 后，错误得到解决。
