EO.WebBrowser is a web browser engine based on Google's Chrome project but with native .NET programming interface --- don't worry, it's not a wrapper around the Chrome browser installed on your machine. In fact EO.WebBrowser has the whole browser engine embedded inside a single .NET DLL. In another word, it has zero external dependency. Just reference and use.
