Wiki Creole (http://wikicreole.org) is a standardized markup designed at WikiSym 2006 with the goal is to get all wiki engines to share a common wiki syntax.
This is a .NET library which given a string in WikiCreole will convert it to HTML.
This C# .NET library is fully WikiCreole 1.0 compliant, supporting tables, image links as well as the ability to customize the attributes of html tags to be able to support CSS.
It is available via http://nuget.org as WikiCreole.NET library
It also supports the extensions of superscript, subscript, underline and monospace.
