asp.net - HTML Sanitizer for .NET

Question

I'm starting a project that will be public facing using asp.net mvc. I know there are about a billion php, python, and ruby html sanitizers out there, but does anyone have some pointers to anything good in .net? What are your experiences with what is out there? I know stackoverflow is a site done in asp.net that allows freeform HTML, what does it use?

HtmlSanitizer

A fairly robust sanitizer. It understands and can clean inline styles, but doesn't have a parser that can deal with <style> blocks, so it strips them. It's certainly up to and probably beyond the level that Microsoft's AntiXSS was at, before it was abandoned.
