I posted an answer on Stack Overflow and I'm not sure why it was deleted. I went back to look at it and I didn't see anything wrong with my answer that would cause it to be deleted.
You answer doesn't answer this question, and seems to only advertise your own tool, hence why it would have been deleted:
Perhaps you could have linked to your project as a comment, but to be honest I'm not sure whether this kind of advertising of your own products is entirely appropriate.
Your answer is a link-only answer which is discouraged. Links break and such posts get useless.
Besides that you are only promoting a tool you developed. That is discouraged too.
