How do you force a line break between two words in a XAML-declared Label?

Question

Maybe I'm not using the right key words, but all my searches are coming up empty. How do you force a line break?

I can tell you that none of the following work:

<Label
    Content="Line&br;Break:" />

<Label
    Content="Line<br />Break:" />

<Label
    Content="Line
    Break:" />

<Label
    Content="Line\nBreak:" />

Can someone share this closely guarded secret?

Thanks.

EDIT:

Okay, never mind. I finally found it.

<Label
    Content="Line&#x0a;Break:" />

Definitely not easy to guess!

EDIT 2:

Okay, and now to get the text to be right-justified, I went with this:

<Label
    <TextBlock
        TextAlignment="Right"
        Text="Line&#x0a;Break:" />
</Label>

Thanks to Julien for the idea of using a TextBlock.

Answer 1

If you only need to display text, you can use a TextBlock instead of a Label:

<TextBlock>
  Line<LineBreak/>Break:
</TextBlock>

If you really need a Label (e.g. you need to respond to a click event), you can wrap the above code inside a Label.

Answer 2

I'd do this:

<StackPanel>
    <Label>First line</Label>
    <Label>Second line</Label>
</StackPanel>

If the formatting gets really involved, I'd use FlowDocumentScrollViewer.
