Question

i need a C# library about strict HTML validation and filtering

Answer 1

I don't think any such thing exists, but it doesn't seem like it would be that hard to do a validation API that utilizes the w3C validator behind the scenes.

What kind of filtering are you talking about? Your question is very vague...

Answer 2

Jeff Atwood posted some code for HTML tag filtering and sanitizing a while back. From your brief description it sounds like something you might want to look into.
