This is part of a series on New WPF Features
In previous versions, adding a custom dictionary was an unsupported scenario. You could still do it but it required writing a bunch of code.
In this release, we have provided suport for adding custom dictionaries.
<RichTextBox FontSize="24" SpellCheck.IsEnabled="true" >
<Paragraph>Some Names: Zorig Lester </Paragraph>
<Paragraph>Misspelled: Zorg BlahBlah </Paragraph>
The dictionaries are plain text files and list the words to be updated.
For a non default locale (en-us) you can specify the locale ID at the top (#LID localeID). In the pic above, we are using the locale 2057 which corresponds to english-UK.
