从.NET 4.0项目创建.NET 3.5版本

Question

我有一个在4.0中开发的WCF应用程序.它使用文件路径的设置(例如日志文件的路径).当我想构建一个3.5版本时,它给我一个ConfigurationErrorException,它读取:

"为userSettings/WCF_SmartStatsHost.Properties.Settings创建配置节处理程序时出错:无法加载文件或程序集'System,Version = 4.0.0.0,Culture = neutral,PublicKeyToken = b77a5c561934e089'或其依赖项之一.系统不能找到指定的文件.(C:\ Users\Pierre\Documents\Visual Studio 2010\Projects\WCF_SmartStats\WCF_SmartStatsHost\bin\Debug"

我已经检查并重新检查了文件路径等,但它看起来比它更具技术性.

这是堆栈跟踪:

任何帮助,将不胜感激.

如果它们已设置为"Specific version = true",请检查您的引用(在解决方案资源管理器中右键单击属性).将其更改为false,然后重试.

这是您的错误消息中的重要部分:
