webkit.net browser doesn't appear

Question

I started using this open source project. I tried this:

 WebKitBrowser browser = new WebKitBrowser();
        browser.DocumentText =
    "<h1><a href=\"http://google.com\">Hello, World!</a></h1>";

and this:

WebKitBrowser browser = new WebKitBrowser();
        browser.Navigate("https://emailhunter.co/");

I also tried Webkit.net opening new tabs and windows this. In first 2 cases nothing happens. I can 't even see a window. In last situation i can't compile it.

Any suggestions appritiated.
