Question

首先，我之前设法让我的64位测试网络应用程序之一在这台机器上运行（当我为这个项目进行原型设计时）。我已经在32位工作了几个星期，并意识到我需要将应用程序切换到64位，当我做（在项目中将目标平台设置为x64）并重新部署时，它停止运行。

我上次花了好几天才得到64位工作，而且我不确定这次我上次错过了什么。

我正在IIS下发布并调试。

我收到BadImageFormatException并显示消息：“无法加载文件或程序集'GEMS.Web'或其依赖项之一。尝试加载格式不正确的程序。”

此应用程序引用64位和32位程序集。我在IIS中的应用程序池中将“启用32位应用程序”设置为true。

我正在使用在64位Win 7计算机上运行的VS.NET 2012，IIS 7.5。

Answer 1

使用以下方法更改IIS以处理64位处理：工具|选项|项目和解决方案|网站项目|使用64位版本的IIS Express

Answer 2

如果您没有使用任何本机Win32库，则应该为程序集定位Any CPU，而不要弄乱IIS中的启用32位应用程序设置（将其保留为false）

64位ASP.NET MVC应用程序将无法运行
