asp.net – ActivationManager构建过程中的异常？

在VS 2010中构建网站项目时，我收到以下异常：

The pre-application start initialization method Run on type WebActivator.ActivationManager  threw an exception with the following error message: Exception has been thrown by the target of an invocation..

我该怎么去调试？当我在VS.NET和命令行(例如，通过NAnt / MSBuild)中构建时，会发生这种情况。

解决方法

要解决这个问题，您需要将-errorstack参数提供给aspnetcompiler。那么当它失败时，你不仅可以获得你现在看到的异常的堆栈跟踪，还可以获得它正在包装的InnerException。例如，当构建错误是由于未加载Cassette dll的问题引起的时，这里是输出：

bActivator.ActivationManager threw an exception with the following error message
: Exception has been thrown by the target of an invocation..
