WPF Major Breaking Changes in Feb 2006 CTP

This is intended as a quick guide to the major breaking changes that will affect Windows Presentation Foundation applications, rather than providing an exhaustive list:

• Schemas have changed for WPF and XAML. Instead of:
  https://schemas.microsoft.com/winfx/avalon/2005
  use:
  https://schemas.microsoft.com/winfx/2006/xaml/presentation
  Instead of:
  https://schemas.microsoft.com/winfx/xaml/2005
  use:
  https://schemas.microsoft.com/winfx/2006/xaml
• We've tightened up the definition of Grids - make sure you wrap ColumnDefinition and RowDefinition elements within a corresponding Grid.ColumnDefinitions or Grid.RowDefinitions element. (Previously you couldn't use this syntax within templates.)
• SinglePageViewer is now FlowDocumentPageViewer (this makes sense, since the viewer is used for FlowDocuments!)
• The relative source binding syntax has changed: replace
  {Binding Path=foo, RelativeSource=/TemplatedParent}
  with
  {Binding Path=foo, RelativeSource='{RelativeSource TemplatedParent}'}

UPDATE: Karsten and I are less well synchronized than normal this week since we're temporarily in different continents. He's posted a separate list of breaking changes on his blog. Check both locations out - he's got a few that I don't have and vice versa.

UPDATE 2: Rob has a nice tool that makes some of these updates automatically. He also mentions the external assembly referencing breaking change (another one I missed - doh!)

  So these are the breaking changes.
  
  What kinds of non-breaking changes are in the Feb CTP?
  
  Im thinking in particular of WPF changes.

  New features, you mean? I can't think of any further additions off-hand - we're really locked and loaded for RTM at this point.

  I'm more curious about what other breaking changes there are.

  How do you translate
  
   {Binding RelativeSource=/TemplatedParent/TemplatedParent}
  
  into the new syntax for RelativeSource?
  
  I tried using
   {Binding RelativeSource={RelativeSource Mode=TemplatedParent, AncestorLevel=2}}
  
  But it doesn't work.

  George,
  The following should work:
  {Binding RelativeSource={RelativeSource TemplatedParent}, Path=TemplatedParent}

  any idea why this doesn't work? <Window x:Class="TemplateExample.Window1"    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"    Title="TemplateExample" Height="300" Width="300"    >  <Window.Resources>    <XmlDataProvider x:Key="Index" XPath="/Chapters">      <x:XData>        <Chapters xmlns="">          <Chapter>            <Title>Title 1</Title>            <Name>Name 1</Name>          </Chapter>          <Chapter>            <Title>Title 2</Title>            <Name>Name 2</Name>          </Chapter>        </Chapters>      </x:XData>    </XmlDataProvider>    <DataTemplate x:Key="MyTemplate">      <StackPanel>        <TextBox FontSize="14" FontWeight="Bold" FontStyle="Oblique" Text="{Binding XPath=Title}" />        <TextBox FontSize="14" FontWeight="Bold" FontStyle="Italic" Text="{Binding XPath=Name}" />      </StackPanel>    </DataTemplate>  </Window.Resources>  <StackPanel>    <ListBox Background="Aqua"             ItemsSource="{Binding Source={StaticResource Index}, Path=Chapter}"             ItemTemplate="{StaticResource MyTemplate}" />  </StackPanel> </Window>
