我正在尝试运行我在 Visual Studio 2012 中创建的 WCF 服务。

我在页面中遇到错误。

我用谷歌搜索了一下,我已经尝试了几件事。1) 在应用程序池中启用 32 位应用程序 2) 在项目属性中将目标设为“任何 CPU” 3) 删除临时文件、回收应用程序池、重置 IIS 等

如果您有更多建议,请提供帮助。

看起来您正试图将 64 位程序集加载到 32 位应用程序池中。我这样说是因为我C:\Windows\Microsoft.NET\Framework\v4.0.30319\在堆栈跟踪中看到了。如果它是 64 位应用程序池,它将使用Framework64. 禁用“启用 32 位”并重试。
