C# Library for Grammar and Spell Checking - Arik Poznanski's Blog

I recently had the idea to create a plug-in for Windows Live Writer that will provide grammar checks in addition to the built-in spell checks. As I’ve showed before, creatingplug-ins for Windows Live Writer is easy, the problem was to get the code for doing the grammar checking. I’ve found this wonderful site named “After the Deadline” that provides a web based API for both grammar and spell checking, free for non-commercial use!
