wpf 到底错在哪了？

[booma]

<Window
xmlns='http://schemas.microsoft.com/winfx/2006/xaml/presentation'
Title='Hello World!'>
<Button>Hello World!</Button>
</Window>

xaml 的文件内容如上，保存后在浏览器上会出错如下错误：

Startup URI: D:\EBOOK\WPF\Essential.WPF\HelloWorld.xaml
Application Identity: file:///C:/WINDOWS/Microsoft.Net/Framework/v3.0/WPF/XamlViewer/XamlViewer_v0300.xbap#XamlViewer_v0300.application, Version=3.0.0.0, Culture=neutral, PublicKeyToken=c3bce3770c238a49, processorArchitecture=msil/XamlViewer_v0300.exe, Version=3.0.0.0, Culture=neutral, PublicKeyToken=c3bce3770c238a49, processorArchitecture=msil, type=win32

不知道是怎么回事？

没装 07 帮UP下. 无法实验.. 记得给分~

没装 07 什么意思？
像这种的就可以直接打开看到
<RichTextBox FontFamily="Palatino Linotype" FontSize="72" SpellCheck.IsEnabled="True" Typography.HistoricalLigatures="True" Typography.NumeralStyle="OldStyle" Typography.DiscretionaryLigatures="True" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" />

代码没问题 在XAMLPad上正常显示

System.Security.SecurityException
是.NET FRAMEWORK的SECURITY问题,设置为完全信任环境

加一段代码试试

using System.Security.Permissions;
[assembly: PermissionSetAttribute(SecurityAction.RequestMinimum, Name="Internet")]
[assembly: PermissionSetAttribute(SecurityAction.RequestOptional,Unrestricted=true)]

帮顶

这是因为不管是松散的XAML文件，还是XBAP应用（WPF Browser Application），
如果是在浏览器（IE）中运行的化，都是运行在WPF Internet Sandbox沙箱中，
因而不具备创建窗口(Window)的权限，具体细节可以参考：
