Question

我希望使用企业库日志记录5登录我的SSIS 2008，因此我创建了一个类库项目，添加了所有企业库日志记录依赖项并编写了兼容的App.Config。我通过创建一个控制台应用程序验证了我的记录器库的一切正常，添加我的记录器库作为参考并开始使用它进行记录 - 所有工作都没有问题。

现在，当我在我的SSIS项目（内部脚本任务）上执行相同的过程时，我收到以下错误：

Microsoft.Practices.ServiceLocation.ActivationException: Activation error occured while trying to get instance of type LogWriter, key "" ---> Microsoft.Practices.Unity.ResolutionFailedException: Resolution of the dependency failed, type = "Microsoft.Practices.EnterpriseLibrary.Logging.LogWriter", name = "(none)".
Exception occurred while: while resolving.
Exception is: InvalidOperationException - The type LogWriter cannot be constructed. You must configure the container to supply this value.
-----------------------------------------------
At the time of the exception, the container was:

  Resolving Microsoft.Practices.EnterpriseLibrary.Logging.LogWriter,(none)
 ---> System.InvalidOperationException: The type LogWriter cannot be constructed. You must configure the container to supply this value.

我不理解这一点，我做了我能想到的一切：

引用我的记录器库
添加到我的脚本任务App.Config，其内容与我之前尝试过的App.Config相同。
检查我的脚本任务和类库是否在相同的框架版本下工作

通常这个错误与App.Config问题有关但我从我的Tester项目中获取完全相同的App.Config所以我不确定它为什么会发生。

你知道我该如何解决它？

SSIS 2008不适用于企业库日志记录
