Does anyone know if there's a native port of HTML Tidy available for .NET? In Sourceforge, there's a TidyNet project - which hasn't been updated since 2005 and seems like a wrapper only. Java port seems to exist as recent JTidy project.
HTML Tidy project page: http://tidy.sourceforge.net/
You are right, the Tidy.NET hasn't been updated in a while.
An alternative is TidyForNet Links on that page to the source code in SVN.
