在 .NET 4 中结合使用旧安全策略和动态操作

Question

我正在尝试一起使用旧的 .NET 代码，该代码需要设置旧的安全策略支持：

<NetFx40_LegacySecurityPolicy enabled="true" />

并且还托管 IronPython（并且可能在某些地方使用 dynamic 关键字）。

我找不到同时使用它们的方法。如果我将上述选项添加到 app.config 文件中，则会出现异常

动态操作只能是 在同质 AppDomain 中执行。

如果我不添加该选项，我会得到

此方法显式使用 CAS 策略，该策略已被 .NET Framework 废弃。为了出于兼容性原因启用 CAS 策略，请使用 NetFx40_LegacySecurityPolicy 配置开关。请参阅http://go.microsoft.com/fwlink/?LinkID=155570了解更多信息。

有什么办法可以解决这个问题吗？

值得一试，不要设置 LegacySerurityPolicy 并尝试为您的应用程序提供应用程序清单，而不是类似于以下内容。
