Question

How can I use tab and carriage return characters in a WPF XAML resource dictionary?

This doesn’t work for me:

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                xmlns:system="clr-namespace:System;assembly=mscorlib"
                >

<system:String x:Key="test_Key">Tab doesnt work\tTest\rTest</system:String>
</ResourceDictionary>

when I retrieve this via FindResource(“test_key”), both the tab and carriage return characters are removed.

The XAML parser uses whitespace normalisation (as per MSDN) if you want to avoid this add xml:space="preserve" to your XML as such:

<system:String x:Key="test_Key" xml:space="preserve">Tab doesnt work&#x09;Test&#x0d;Test</system:String>
