Overview

The WPF SpellChecker control provides spell checking functionality to your application. Error words are underlined automatically and can be corrected through suggestions in the context menu. The control can perform spell checking in text editor controls and offers built-in features to correct error words, ignore special words, and add new terms to the dictionary. It also supports using a custom dictionary to check spelling.

I am really thankful for the wonderful set of controls for WPF. I was able to deliver things on time and could focus on core business logic rather than control development.
