Welcome to Microsoft Q&A!
The Html style does not support
<pre> based on my test .
I even tried to use HtmlLabelPlugin , but still no luck , same result .
If you want to display the html perfectly , I suggest you use WebView .
var browser = new WebView(); var htmlSource = new HtmlWebViewSource(); htmlSource.Html = @"<html><body> <pre>Hello user<BR/>How are you</pre> </body></html>"; browser.Source = htmlSource; Content = browser;
