背景

我有一个构建后事件，我用它来生成一些包含我们应用程序当前版本号的批处理文件。该事件调用一个批处理文件，该文件调用一个托管应用程序，该应用程序加载程序集并使用反射来查找其版本信息。

问题

当构建后事件在本地运行时，一切都很好。当它在我们的自动构建过程下运行时，我在日志中看到以下错误。我对代码访问安全一无所知，希望有人能迅速指出问题所在。

您使用的是哪个版本的框架？旧版本不太信任网络共享 - 因此您可能需要使用“ caspol ”来启用信任（或在运行文件之前将文件移动到本地）。最近，该框架确实信任映射的共享（例如Q:\），但不信任\\someserver\whatever没有“caspol”调整的 UNC 共享 ( )。

不过，最简单的选择是从本地驱动器而不是通过网络运行 exe。
