我尝试在VS2015中使用Enterprise Library 6.0中的日志记录，并弹出以下异常。 VS2015的引用中已经添加了引用Microsoft.Practices.EnterpriseLibray.Common。

帮我弄清楚
您引用的 DLL 可能是不同的版本，或者可能根本没有被引用。
- 尝试删除并重新添加引用。
- 尝试在属性中将
设置为Version Specific。false
有同样的问题，通过将参数“启用 32 位应用程序”设置为“true”（在 iis 应用程序池的高级设置中）修复。
正如 @ViVi 已经提到的，尝试再次添加引用并重建您的项目。
只是在这里记录我发生的事情。
对我来说，错误是：
无法加载文件或程序集“Microsoft.Practices.EnterpriseLibrary.Common，Version=5.0.514.0，Culture=neutral，PublicKeyToken=31bf3856ad364e35”或其依赖项之一。
我的解决方案中没有引用此 DLL。
事实证明，在其他一些项目中添加了对
