Could not load file or assembly 'MySql.Data.CF,

  • Could not load file or assembly 'MySql.Data.CF, Version=6.4.4.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d, Retargetable=Yes' or one of its dependencies. The given assembly name or codebase was invalid. (Exception from HRESULT: 0x80131047

    • I solved it. The problem is  due to dll problem. 

      I copy the dll to bin folder then it works fine with no issue.

      博主的解决办法 先在项目里删除引用MySql.Data.CF ,然后到项目文件夹删除bin下面的 MySql.Data.CF，貌似ASP.NET会自动读取BIN下面的所有DLL，导致冲突并产生报错，打开任何一个页面都报错
