我有一些已部署的Windows窗体应用程序停止在特定计算机上运行。重新部署所有.exes和.dll的重新安装不会对解决错误产生任何影响。
在应用程序的第一次数据库访问中，错误如下：
Microsoft .NET Framework

据我所知，这使得codefluent寻找MySql.Data而不是默认的System.Data（Sql Server）......
可能导致winforms应用程序在特定计算机上进行特定部署的原因是什么呢？
错误堆栈跟踪的关键点是：

em CodeFluent.Runtime.CodeFluentPersistence.OpenConnection()
OpenConnection转换为System.Data，而不是MySql ....
我应该检查本机的Windows 7操作系统是否会导致这种奇怪的行为，而不是其他具有相同应用程序的Windows 7操作系统正常工作？
