Hi everyone,
I've just released Velocity (http://velocity.silverlakesoftware.com) which is an offline documentation viewer (a lot like Dash for the Mac). It uses CEF and so far everything has been working fantastic. A big thank you to Marshall and the other contributors.
It's written in C# and I used WinForms because that let me use a third party theme to come close to Visual Studio in appearance. I'm using Xilium.CefGlue http://xilium.bitbucket.org/cefglue/ for the .NET wrapper which has also been working out really well.
Thanks!
Jamie
