我正在 ssis 2008 中创建一个集成服务项目，并尝试将我的自定义项目 dll 添加到脚本任务引用并执行包，我遇到了异常提示

Error: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.IO.FileNotFoundException: Could not load file or assembly 'example, Version=1.0.0.0, Culture=neutral, PublicKeyToken=--------' or one of its dependencies.

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [---\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [---\Software\Microsoft\Fusion!EnableLog].

您的问题的简短回答是“是”。

但是，自定义 DLL 需要安装在 GAC 中并在执行包之前添加到 .NET Framework 文件夹中。（验证需要 .NET Framework 副本，执行需要 GAC 副本。是的，这很烦人。）
