Answer 2

This cannot be done using C# only.

WebKit is C++-based, so you'd need at least a C++ wrapper in order to let the browser communicate with your code. Using a mixed-mode C++ DLL that talks to WebKit on one side and to your C# code on the other side should be considered.

The WebKit site does not contain much docs (don't want to criticize, but I couldn't find much there when working with Chromium). Only Apple docs explain plug-ins, but it looks very Apple-oriented. Sorry, not very helpful.
