Form showing nothing. using CefSharp with Windows form in C#

Question

I am trying to show a webpage in a form using C#. I am using CefSharp to show the webpage (as I would like to test & learn how it works). But since I have worked only on inbuilt webbrowser, I have no idea how to get started with CefSharp(Finding it difficult to get any tutorials). I tried to write this code which executes but the form shows nothing in it. Where am I going wrong ? Here is my Code :

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using CefSharp;
using CefSharp.WinForms;

namespace chrometest
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
            Cef.Initialize(new CefSettings());
            var test = new       CefSharp.WinForms.ChromiumWebBrowser("http://www.google.com")
            {
                Dock = DockStyle.Fill,
            };
            this.Controls.Add(test);
        }

        private void Form1_Load(object sender, EventArgs e)
        {

        }
    }
}

Edit : I tried to run the example from https://github.com/cefsharp/CefSharp/tree/cefsharp/41/CefSharp.WinForms.Example When I try to build the solution, it shows a dialog box saying "Restoring Nuget Package cef.redist.x64 3.2454.1317" with a progresss bar which takes hell lot of time to complete but never completes and after sometime it hangs.
