How to call a set phone number from a button click using Xamarin iOS

Question

Hello I am working on a app that needs to call a certain phone number when the button is clicked i am using Xamarin iOS to do this here's my code:

using Foundation;
using System;
using System.CodeDom.Compiler;
using UIKit;

namespace appname
{
    partial class HomeView : UIViewController
    {

        public HomeView (IntPtr handle) : base (handle)
        {
            phonebutton.TouchUpInside += delegate {
                var url = new NSUrl("tel:12345678");
                UIApplication.SharedApplication.OpenUrl(url);
            };
        } 
    }
}

I am new to Xamarin iOS so any links of examples would be so amazing!
