“无法加载文件或程序集或其依赖项之一。 试图加载格式不正确的程序。”

Question

在 VS 中调试时，在 VS 中启动调试时会引发错误。

错误如下：

Could not load file or assembly 'p4dn, Version=1.0.1.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. An attempt was made to load a program with an incorrect format.

当我创建一个使用“p4dn.dll”的 C# 项目时，不会出现此错误。

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？

Answer 1

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

Answer 2

转到各自 ==> 站点应用程序池，

单击 ==> 高级设置

     Change value of ==> "Enable 32-Bit Applications" from  False to True 

Answer 3

我在尝试使用 IIS Express 8.0 运行（调试）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。

出现此问题是因为 Visual Studio 运行 32 位版本的 IIS Express。 我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”，然后输入您站点的 url。

要进行调试，请转到调试 > 附加到进程...，然后选择正在运行的 IIS Express 实例。

Visual Studio 团队确实应该将其作为项目属性中的一个选项。

Answer 4

-为您的网站创建一个新的 IIS 池 -为此池启用 32 位

Answer 5

Asp.Net 上的 C# 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，它不起作用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 IIS 上将应用程序池从 v2.0 更改为 V4.0 后，错误得到解决。
