How to put a new line into a wpf TextBlock control?
you must use
< SomeObject xml:space="preserve" > once upon a time ... this line will be below the first one < /SomeObject>
Or if you prefer :
<SomeObject xml:space="preserve" /> once upon a time... this line below < / SomeObject>
watch out : if you both use &10 AND you go to the next line in your text, you'll have TWO empty lines.
