trying it in code reveals all
Where we stand appears to be that the compiler is fine with it, but it causes a runtime exception. MS folks, please give us this property. If not in TextBox, then in RichTextBox.

AMEN to this!!! Videos certainly have their audiences, but for developers, text-based info, with screenshots where appropriate, is infinitely more useful than videos.

To USE or NOT to use?
Can anyone tell me where we are with this property.  Documentation above contradicts itself?

Thomas Lee
I decided to use it, but didn't use it. or did i?
the document says both to use it in SL4 and to not use it. so which one is it?

thanks.
