Use StringFormat to add a string to a WPF XAML binding

Here's an alternative that works well for readability if you have the Binding in the middle of the string or multiple bindings:

<TextBlock>
  <Run Text="Temperature is "/>
  <Run Text="{Binding CelsiusTemp}"/>
  <Run Text="°C"/>  
</TextBlock>

<!-- displays: 0°C (32°F)-->
<TextBlock>
  <Run Text="{Binding CelsiusTemp}"/>
  <Run Text="°C"/>
  <Run Text=" ("/>
  <Run Text="{Binding Fahrenheit}"/>
  <Run Text="°F)"/>
</TextBlock>

Please note that using StringFormat in Bindings only seems to work for "text" properties. Using this for Label.Content will not work

Your first example is effectively what you need:

<TextBlock Text="{Binding CelsiusTemp, StringFormat={}{0}°C}" />
