IE打开XAML文件报错
求教：
初学WPF，机器上安装了VS2008和VS2010
帖了段代码到XAML文件里，用IE7打开报错
XAML代码如下：
XAML:
<Button xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" Content="OK" />
出错信息：

[解决办法]
XAML文件格式错误，IE不能正确解析，你应该这样写：
<Canvas xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Button Width = "100" Height = "30" Content="OK"/>
</Canvas>
