Fetching DeviceId through TelephonyManager in Xamarin.Android

Question

public string GetIdentifier()
        {

            Android.Telephony.TelephonyManager mTelephonyMgr;
            mTelephonyMgr = (Android.Telephony.TelephonyManager)Forms.Context.GetSystemService(Forms.Context.TELEPHONY_SERVICE);
            return mTelephonyMgr.DeviceId;
        }

Trying to get DeviceId through above code but TELEPHONY_SERVICE is giving compile time error in Visual Studio(Xamarin +Android).How to correct this? Please see the image attached for reference.ErrorImage

Its a little different in Xamarin Android

        Android.Telephony.TelephonyManager mTelephonyMgr;
        mTelephonyMgr = (Android.Telephony.TelephonyManager)Forms.Context.GetSystemService(Android.Content.Context.TelephonyService);
        return mTelephonyMgr.DeviceId;

Forms.Context is now obsolete. This code will raise a compiler warning. – dylanT Jan 12 '18 at 06:46
Use Android.App.Application.Context instead – chandravadan Sep 09 '20 at 18:10
