One of the features that impressed PDC attendees was the built-in spell checker in Windows Presentation Foundation. Activating it is just as simple as setting the IsSpellCheckEnabled property to true on a TextBox or RichTextBox control.
<TextBox IsSpellCheckEnabled='True'>This text is wronw.</TextBox>
<FlowDocument><Paragraph>This text is also wronw.</Paragraph></FlowDocument>
Users will get red 'squigglies' under the misspelled words, and the context menu will come up with suggestions. Was that easy or what?
