WPF ClickOnce 和部分信任问题

Question

如何让我的应用程序部署正常工作？

我使用 Visual Studio 2010 创建了一个新的简单 WPF 项目，并对项目的属性进行了以下修改:
-> 签名:创建测试证书并签署两个程序集和 list 。未选中“仅延迟签到”框
-> 安全:选中“启用单击一次安全设置”和单选按钮“这是部分信任设置”。区域:“本地 Intranet”。
-> 安全，高级:使用选定的安全设置调试这个应用程序(我选择了这个)。

开始调试时，我收到“System.Security.Permissions.SecurityPermission，mscorlib，Version=4.0.0.0，Culture=neutral，PublicKeyToken=b77a5c561934e089”类型权限的请求失败。

安装时，应用程序将被安装，但启动时没有任何 react 。在另一台计算机上，将显示 bla bla 已停止工作(启动实用程序)。

操作系统:Windows 7。

通过一些实验，我发现添加标志 非托管代码 到安全权限 解决了这个问题。为什么一个简单的 WPF 应用程序(一个新创建的 hello world)需要调用非托管代码？这是一个像火山一样大的安全漏洞。

感谢您的任何提示

派对迟到了，但这是我发现的(虽然偶然发现了同样的问题)。

似乎 WPF Window确实需要 UnmanagedCode允许。

而且，这里是异常的堆栈跟踪，当通过 ClickOnce 在部分信任中部署的 WPF 应用程序运行时。注意调用DemandUnmanagedCode SecurityHelper的功能来自 Window 的构造函数:

  InnerException: System.Security.SecurityException
       Message=Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

而且，这是完整的 StackTrace:
