How to use UserControl in ASP.NET MVC?

1. Create UserControl as same as in the webforms. But change base class from System.Web.UI.UserControl to System.Web.Mvc.ViewUserControl

    public partial class TestUserControl : System.Web.Mvc.ViewUserControl
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            this.Label1.Text = "Loaded";
        }
    }

2. Put this UserControl all related files into Views/Shared folder
3. Then able to load by Partial view

@Html.Partial("TestUserControl");
