Download the binary package and unzip it. Drag the WebKitBrowser.dll to Toolbox to add it there, and drag one from Toolbox to a form. All the files in bin folder of package is required for the browser to operate (All except the subfolders, the WebKitBrowserTest.exe, and WebKitBrowser.dll which is already referenced, WebKit.Interop.dll which is generated based on the reference.), so add them to project, configure Copy to output directory and set Build action Content. Putting these files in build output folder is sufficient for debugging.
