I've seen a few COM controls which wrap the Gecko rendering engine (GeckoFX, as well as the control shipped by Mozilla - mozctlx.dll). Is there a wrapper for Webkit that can be included in a .NET Winform application?
I've just release a pre-alpha version of CefSharp my .Net bindings for the Chromium Embedded Framework.
Check it out and give me your thoughts: https://github.com/chillitom/CefSharp (binary libs and example available in the downloads page)
update: Released a new version, includes the ability to bind C# objects into the DOM and more.
update 2: no-longer alpha, lib is used in real world projects including Facebook Messenger for Windows, Rdio's Windows client and Github for Windows
