A:

Header="Student Details&#10;Of Application" or Header="Student Details&#x0a;Of Application" will also work.  Or if you're not inserting into a string you can also do something like. 
<TextBlock>
Line<LineBreak/>Break
</TextBlock>

but personally I just use the codes shown in the first two examples.  Also keep in mind the xml will retain whitespace, so you can do like Header="  Details of&#10;Student Application" for alignment purposes if TextAlignment property isnt available.  Hope this helps.
