The NetSpell project is a spell checking engine written entirely in managed C# .net code. NetSpell's suggestions for a misspelled word are generated using phonetic (sounds like) matching and ranked by a typographical score (looks like). NetSpell supports multiple languages and the dictionaries are based on the OpenOffice Affix compression format. The library can be used in Windows or Web Form projects. The download includes an English dictionary with dictionaries for other languages available for download on the project web site. NetSpell also supports user added words and automatic creation of user dictionaries. The package includes a dictionary build tool to build custom dictionaries.

NetSpell dictionaries are based on the OpenOffice dictionary format. You can use the Dictionary build tool to convert OpenOffice dictionaries to the NetSpell format. OpenOffice dictionaries can be downloaded here: https://lingucomponent.openoffice.org/dictionary.html
