WPF ClickOnce和部分信任问题

Question

如何让我的应用程序部署工作？

我使用Visual Studio 2010创建了一个新的简单WPF项目,并在项目的属性中进行了以下修改: - >签名:创建测试证书并将两个程序集都标记为清单.没有选中"仅延迟签名"框 - >安全性:选中框"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:"本地内联网". - >安全性,高级:使用所选的安全设置调试此应用程序(我选择此项).

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

安装时,将安装应用程序,但启动它时没有任何反应.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,我发现将标志UnmanagedCode添加到SecurityPermission解决了这个问题.为什么需要一个简单的WPF应用程序(一个新创建的hello world)来调用非托管代码？这是一个像火山一样大的安全漏洞.

谢谢你的任何提示

聚会迟到了，但这是我发现的（同时偶然发现同样的问题）。

看来WPFWindow 确实需要UnmanagedCode许可。

摘自C# 中的 Pro WPF 4.5：.NET 4.5 中的 Windows Presentation FoundationMatthew MacDonald 的

并且，这里是运行在部分信任中通过 ClickOnce 部署的 WPF 应用程序时的异常堆栈跟踪。注意从构造函数DemandUnmanagedCode调用函数SecurityHelperWindow：

\n\n

  InnerException: System.Security.SecurityException\n       Message=Request for the permission of type \'System.Security.Permissions.SecurityPermission, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089\' failed.\n       Source=mscorlib\n       StackTrace:\n            at System.Security.CodeAccessSecurityEngine.Check(Object demand, StackCrawlMark& stackMark, Boolean isPermSet)\n            at System.Security.CodeAccessSecurityEngine.Check(CodeAccessPermission cap, StackCrawlMark& stackMark)\n            at System.Security.CodeAccessPermission.Demand()\n            at MS.Internal.SecurityHelper.DemandUnmanagedCode()\n            at System.Windows.Window..ctor()\n            at WPFClickOnceDeploySample.MainWindow..ctor()\n

而且，这是完整的 StackTrace：
