Recommendation for WinForms Spell Checker

Question

I have a WinForms text editing application in a large RichTextBox control.

Can anyone suggest the easiest (and hopefully the cheapest) way to add spell checking to a RichTextBox control?

Answer 1

One option is to use hosted content and place a WPF control that offers spell checking. For example, WPF RichTextBox has a property SpellCheckthat you can enable.

Please note that WPF uses its own spell checker and does not require Microsoft Office.
