【问题描述】：
首先，我之前设法让我的一个 64 位测试网络应用程序在这台机器上运行（早在我为这个项目设计原型时）。我已经在 32 位上工作了几个星期，并意识到我需要将应用程序切换到 64 位，当我这样做（在项目中将目标平台设置为 x64）并重新部署时，它停止运行。
上次我花了几天时间才让 64 位工作，但我不确定这次我错过了什么。
我在 IIS 下发布和调试。
我收到带有以下消息的 BadImageFormatException：“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。”
此应用同时引用 64 位和 32 位程序集。我已在 IIS 的应用程序池中将“启用 32 位应用程序”设置为 true。
我使用的是 VS.NET 2012，IIS 7.5，在 64 位 Win 7 机器上运行。
以下来自程序集负载跟踪：
