With .NET 4.0 Microsoft will bring up a improved version of XAML. This arcitle shows you the language enhancements they made.
If you want to create an object reference today you need to do a databinding and declare the source with an ElementName. In XAML 2009 you can use the new {x:Reference}
markup extension
If you want to add objects of simple types like string or double to a resource dictionary today you need to map the needed clr-namespaces to an XML namespaces. In XAML 2009 we a lot of simple types that are included in the XAML language.
In XAML 2006 objects must have a public default constructor to use them. In XAML 2009 you can pass constructor arguments by using the x:Arguments
syntax.
When you have a type that has no public constructor but a static factory method you had to create that type in code in XAML 2006. With XAML 2009 you can use the x:FactoryMethod
x:Arguments attribute to pass the argument values.

Can I make use of these new features in Visual Studio 2008? When will the new .NET 4.0 features of WPF be available for developers outside Microsoft?

They are all part of .NET 4.0. You need Visual Studio 2010 to use it. You can download a CTP version from here: http://www.microsoft.com/downloads/details.aspx?FamilyId=922B4655-93D0-4476-BDA4-94CF5F8D4814&displaylang=en. It's a virtual PC image. The beta version that will be released soon will be an installable version.

Do the non-default constructor arguments has to be in order of the consctructor signature? Or how do I specify which arguments are which? (And how does it work together with optional arguments?)

Nice changes, especially the added namespaces, but overall I wouldn't call them earth-shattering. Would be nicer to see simple arithmetic in XAML for example.

Hi Theo,
you are right. I often missed arithmetic functions in XAML too. Maybe there is another clever way to do such things - for example with a MarkupExtension.

Hi Nayak14,
unfortunately it is not possible. The new XAML features are part of .NET 4.0 and this is only included in VS2010. You can download the free Beta 2 Bits and get startet.

How do you enable xaml 2009 in vs2010 beta 2? From the list of schemas I am only seeing http://schemas.microsoft.com/netfx/2009/xaml/presentation but no http://schemas.microsoft.com/netfx/2009/xaml
I read somewhere that using the /winfx/2006/xaml ns should just work but that doesn't seem to be the case.

Hi Very nice article, i am using VS2010 C# expression Edition
When i am using this markup
<Label Target="{x:Reference firstName}">FirstName</Label>
<TextBox x:Name="firstName" />
i got warning "Service Provider is Missing the INameResolver Service"
Any idea how to resolve this???

Commented on 18.November 2010 |
Here is the explanation from Adam Nathan's WPF 4 unleashed book:
"The x:Reference markup extension is often mistakenly associated with the XAML2009
features that can only be used from loose XAML at the time of this writing. Although
x:Reference is a new feature in WPF 4, it can be used from XAML2006 just fine as long as your project is targeting version 4 or later of the .NET Framework.
One glitch is that the XAML designer in Visual Studio 2010 doesnât properly handle x:Reference, so it gives the following design-time error that you can safely ignore:
Service provider is missing the INameResolver service"
