There is nothing more frustrating than recording a course for one hour, and then a week later during editing noticing a spelling mistake. Looks like I found a very handy Visual Studio extension, a spell checker!
Download directly from the link above, or by using Visual Studio. Restart is required.
And type away. The spell checker can be configured.
To read about the configuration options visit the codeplex site, or simply select Spell Check from the Tools tab in you Visual Studio menu.
And as you can see there are a few options available 🙂
