推荐答案

这通常意味着您在的更高版本中编译了一个库. NET Framework，而您试图在针对.NET Framework较低版本的项目中使用它.例如，Firebird客户端是针对.NET 4.0编译的，您不能在.NET 2.0、3.0或3.5项目中使用它.

或者，Firebird客户端库有多个版本，并且您设置了对错误版本的引用.

This usually means that you compiled a library in a higher version of the .NET Framework and you''re trying to use it in a project that is targeting a lower version of the .NET Framework. For example, the Firebird client was compiled targeting .NET 4.0, you cannot use it in a .NET 2.0, 3.0 or 3.5 project.

Or, there are multiple versions of the Firebird client library and you set a reference to the wrong version.
