What is a good HTML editor for WinForms?

Question

HTML

We are looking for an external component (preferably free, although paid is possible) that allows editing HTML (and, optionally, CSS) with code highlighting (and, optionally, intellisense auto-completion and / or auto-closing tags).
So many years of VS on the market, but nothing sane could be found.
Poke your nose, please.

Scintilla - fresher here or here . You can take AvalonEdit from SharpDevelop, but it is WPF and you will have to host it, for example like this .

Answer 2

codemirror.net

Answer 3

Notepad++ looks like a good one, since Troelsen advertises it
