WPF spell checking in text-enabled controls will not work in Windows 10 for languages not in the OS's input language list
Edge
4.6
Not planned
When running on Windows 10, the spell checker may not work for WPF text-enabled controls because platform spell-checking capabilities are available only for languages present in the input languages list.
In Windows 10, when a language is added to the list of available keyboards, Windows automatically downloads and installs a corresponding Feature on Demand (FOD) package that provides spell-checking capabilities. By adding the language to the input languages list, the spell checker will be supported.
- Quirked
- Build-time break
Be aware that the language or text to be spell-checked must be added as an input language for spell-checking to work in Windows 10.
- Not detectable via API analysis
