3) Grids指定行列.
OLD
<Grid>
<ColumnDefinition />
</Grid>.
NEW
<Grid>
<ColumnDefinitions>
<ColumnDefinition/>
</ColumnDefinitions>
</Grid>
4) 数据邦定时必须明确声明邦定对象的属性.
OLD

5) System.Windows.Serialization 现在变成 System.Windows.Markup
6) 用户自定义控件的改变.
OLD
<UserControl>
<UserControl.FixedTemplate>
<Grid>
</Grid>
</UserControl.FixedTemplate>
</UserControl>
NEW
<UserControl>
<Grid>
</Grid>
</UserControl>
7) 多媒体的属性与方法.
MediaElement myME;
OLD
myME.Player.Play();
NEW
myME.Play(); // new
8) 多媒体的行为变化
In the Jan CTP, the following XAML would play the video file until the file ended, or until the MediaElement was GCd.
<MediaElement Source=”a.wmv”>
A MediaElement now stops when it is Unloaded by default.
If MediaElement is incorporated into a visual that does not propagate OnLoaded and Unloaded events (such as VisualBrush), it won’t play automatically on Load. There are a number of work-around for this:
If you want to preserve the old behavior of MediaElement of starting to play at parse time rather than OnLoaded - <MediaElement Source=”foo” UnloadedBehavior=”Play”/>
If you want to use a Storyboard - <MediaElement UnloadedBehavior=”Manual”/>
If you want to use code-behind - <MediaElement UnloadedBehavior=”Manual”/>
9) 在XAML 文件中插入XML Data, XML 源必须包含在一个 x:XData 标签内:
OLD
<XmlDataProvider x:Key="aXmlDP">
<Root xmlns="">
<Number type="int">333</Number>
</Root>
</XmlDataProvider>
NEW
<XmlDataProvider x:Key="aXmlDP">
<x:XData>
<Root xmlns="">
<Number type="int">333</Number>
</Root>
</x:XData>
</XmlDataProvider>
11) SinglePageViewer 改变成 FlowDocumentPageViewer
12) relative源绑定的语法改变：
OLD
{Binding Path=foo, RelativeSource=/TemplatedParent}
NEW
{Binding Path=foo, RelativeSource='{RelativeSource TemplatedParent}'
