Error inflating class android.support.v7.widget.Toolbar after updaring to v7.AppCompat Version 23.3

I am creating a Xamarin Forms Project and using android.support.v7.widget.Toolbar with FormsAppCompatActivity. The code I'm posting below was working with Xamarin.Android.Support.v7.AppCompat Version: 23.0.1.3

But after I upgraded to 23.3.0 this has started throwing Android.Views.InflateException: Binary XML file line #1: Error inflating class android.support.v7.widget.toolbar exception.

Here is my code for MainActivity

[Activity(Label = "AppMob.Client", Icon = "@drawable/icon", MainLauncher = true, ConfigurationChanges = ConfigChanges.ScreenSize | ConfigChanges.Orientation)]
    public class MainActivity : global::Xamarin.Forms.Platform.Android.FormsAppCompatActivity
    {

        protected override void OnCreate(Bundle bundle)
        {
            FormsAppCompatActivity.ToolbarResource = Resource.Layout.toolbar;
            FormsAppCompatActivity.TabLayoutResource = Resource.Layout.tabs;

            base.OnCreate(bundle);

            global::Xamarin.Forms.Forms.Init(this, bundle);

            Xamarin.FormsMaps.Init(this,bundle);
            GoogleAnalyticsHelper.GetGASInstance().Initialize_NativeGAS(Application.Context);  //For GA initialization
            LoadApplication(new App());
        }
}

This is my code for Resource.Layout.toolbar

    <?xml version="1.0" encoding="utf-8"?>
    <android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
