Getting Build/Version numbers from Device Specific Projects

MattButlerMattButler USUniversity ✭✭

PCL Based X.Forms applciation. I have a requirement to display the build number on our "About" screen. I've created a dependency service and found code about how to do this on Android, but haven't a clue about how to get to it on iOS.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Android.App;
using Android.Content;
using Android.OS;
using Android.Runtime;
using Android.Views;
using Android.Widget;
using MyProject.DeviceInterfaces;
using Android.Content.PM;
using Xamarin.Forms;
using MyProject.Android.DeviceSpecificCode;

[assembly: Dependency(typeof(App_Droid))]

namespace MyProject.Android.DeviceSpecificCode
    public class App_Droid : IApp
        public string GetBuildNumber()
            Context context = Forms.Context;
            PackageManager manager = context.PackageManager;
            PackageInfo info = manager.GetPackageInfo(context.PackageName, 0);
            return info.VersionName;

Seems to do the trick on Android. How to do the same thing on iOS. Any help?

    FYI, they both work after a test ;)


    Thanks for sharing Matt
    Do you know how to do it for WinPhone Silverlight 8.1?


    Never mind, is pretty easy

    public class Version : IVersion { public string GetBuildNumber() { return GetBuildNumber(); } }

    public class Version : IVersion { public string GetBuildNumber() { return GetBuildNumber(); } }

    mmm, sorry this code is not working...
