Microsoft.Practices.Unity.ResolutionFailedException

Question

安装WPF应用程序后，我尝试运行该应用程序，它崩溃了，并在事件查看器中记录了下面的错误。有谁有主意吗？

我知道这个线程现在已经很老了，但我只是想说我刚刚遇到了同样的异常，解决方案也几乎一样。

事件查看器的输出与Joe的输出相同。我设法捕获了VS中的异常，它向我显示了一个“为属性Views.MainWindow设置值时出现的ResolutionFailedException”。

然而，真正问题是实体框架试图在一个不存在的目录中构建SqlCE数据库。非常基本，但例外是如此奇怪，我想我会分享我的发现。
