MS SQL C# Extended Stored Procedures

Hello, I have wiriten several components in c# that do some simple HTML manupilation. I was wondering if it is possible to make these c# components into extended stored procedures? From my understanding an extended stored procedure must support several methods so that MS SQL can interact with it ... is there a template in c# for making extended stored procedures ... is it even possible. Thanks in advance.I think if you made a [URL=http://www.dnzone.com/ShowDetail.asp?NewsId=126] com callable wrapper [/url] it would work.
