I’ve updated the WPF Chromium WebBrowser to use the current Awesomium beta version (1.6) and .NET 4.0. It’s still a preview, but you can find the source here on CodePlex. Here are the known issues/problems: 1) Resizing the WebBrowser causes the content to flicker. This appears to be an Awesomium issue, but it needs more investigation (pending support request on Awesomium forum). 2) There is an artifact left behind when scrolling a page; this is a known bug in Awesomium and will be fixed by Awesomium RC1.
