title: HTML Sanitizer for .NET
body: <p>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?</p>
