I would like to use Short Date named string format in WPF.
I tried something like:
<TextBlock Text="{Binding Date, StringFormat='Short Date'}" />
How to do this?

Try this:
<TextBlock Text="{Binding PropertyPath, StringFormat=d}" />
which is culture sensitive and requires .NET 3.5 SP1 or above.
NOTE: This is case sensitive. "d" is the short date format specifier while "D" is the long date format specifier.
There's a full list of string format on the MSDN page on Standard Date and Time Format Strings and a fuller explanation of all the options on this MSDN blog post
However, there is one gotcha with this - it always outputs the date in US format unless you set the culture to the correct value yourself.
If you do not set this property, the binding engine uses the Language property of the binding target object. In XAML this defaults to "en-US" or inherits the value from the root element (or any element) of the page, if one has been explicitly set.
One way to do this is in the code behind (assuming you've set the culture of the thread to the correct value):
this.Language = XmlLanguage.GetLanguage(Thread.CurrentThread.CurrentCulture.Name);
The other way is to set the converter culture in the binding:
<TextBlock Text="{Binding PropertyPath, StringFormat=d, ConverterCulture=en-GB}" />
Though this doesn't allow you to localise the output.

does this always output US format regardless of culture settings?

@CRice - yes it does - for some reason - you have set the culture yourself.

Thanks, pretty bad when the UI "d" outputs different to the xaml.cs "d" of the same date object.

ref the WPF culture bug, I just add this.Language = System.Windows.Markup.XmlLanguage.GetLanguage(System.Globalization.CultureInfo.CurrentCulture.IetfLanguageTag); after initializecomponent in every window;

I added an answer that implements a simple
CultureAwareBinding to help with this issue.Or use this for an English (or mix it up for custom) format:
StringFormat='{}{0:dd/MM/yyyy}'

You can also use 'ConverterCulture=' in your binding - which requires a value to indicate the format. (ConverterCulture='en-GB' is Great Britain).
Use the StringFormat property (or ContentStringFormat on ContentControl and its derivatives, e.g. Label).
<TextBlock Text="{Binding Date, StringFormat={}{0:d}}" />
Note the {} prior to the standard String.Format positional argument notation allows the braces to be escaped in the markup extension language.

The
{} will allow you to use StringFormat='{}Created Date:{0:d}' which otherwise would produce unexpected results.Some DateTime StringFormat samples I found useful. Lifted from C# Examples
DateTime dt = new DateTime(2008, 3, 9, 16, 5, 7, 123);
String.Format("{0:y yy yyy yyyy}", dt); // "8 08 008 2008" year
String.Format("{0:M MM MMM MMMM}", dt); // "3 03 Mar March" month
String.Format("{0:d dd ddd dddd}", dt); // "9 09 Sun Sunday" day
String.Format("{0:h hh H HH}", dt); // "4 04 16 16" hour 12/24
String.Format("{0:m mm}", dt); // "5 05" minute
String.Format("{0:s ss}", dt); // "7 07" second
String.Format("{0:f ff fff ffff}", dt); // "1 12 123 1230" sec.fraction
String.Format("{0:F FF FFF FFFF}", dt); // "1 12 123 123" without zeroes
String.Format("{0:t tt}", dt); // "P PM" A.M. or P.M.
String.Format("{0:z zz zzz}", dt); // "-6 -06 -06:00" time zone

Be aware of the single quotes for the string format. This doesn't work:
Content="{Binding PlannedDateTime, StringFormat={}{0:yy.MM.dd HH:mm}}"
while this does:
Content="{Binding PlannedDateTime, StringFormat='{}{0:yy.MM.dd HH:mm}'}"

If you want add a string with the value use this:
<TextBlock Text="{Binding Date, StringFormat= 'Date : {0:d}'}" />
Comments
Just use:
<TextBlock Text="{Binding Date, StringFormat=\{0:d\}}" />

To add to Chris' answer, I implement my own simple CultureAwareBinding in this way:
public class CultureAwareBinding : Binding
{
public CultureAwareBinding()
{
ConverterCulture = CultureInfo.CurrentCulture;
}
}
And use it in this way in XAML:
<TextBlock
Text="{viewHelpers:CultureAwareBinding Path=ActivationDate, StringFormat=d}"/>
Assuming that the CultureAwareBinding resides in the viewHelpers xmlns.
This way, I ensure that the StringFormat=d is using the correct CultureInfo of the system.
