How to load an extension in a cefsharp WPF project?

问题

I'm trying to load an extension in cefsharp embedded browser in a WPF project. But application freezes while doing so. Here is the code I have been doing to load a very simple extension:

    var setting = new CefSettings();
    setting.RegisterExtension(
            new V8Extension(
                "test",
                "document.body.style.backgroundColor='red'"));
    Cef.Initialize(setting);

Any help would be appreciated.
