    </android.support.v4.widget.DrawerLayout>
</LinearLayout>

using System;
using Android.App;
using Android.Content;
using Android.Runtime;
using Android.Views;
using Android.Widget;
using Android.OS;
using V7Toolbar = Android.Support.V7.Widget.Toolbar;
using Android.Support.V7.App;
using Android.Support.V4.Widget;
using Android.Support.Design.Widget;
namespace Leftdrawerlayout
{
    [Activity(Label = "Leftdrawerlayout", Theme = "@style/Theme.DesignDemo", MainLauncher = true, Icon = "@drawable/icon")]
    public class MainActivity: AppCompatActivity
    {
        DrawerLayout drawerLayout;
        NavigationView navigationView;
        protected override void OnCreate(Bundle bundle)
        {
            base.OnCreate(bundle);
            SetContentView(Resource.Layout.Main);
            var toolbar = FindViewById < V7Toolbar > (Resource.Id.toolbar);
            SetSupportActionBar(toolbar);
            SupportActionBar.SetDisplayHomeAsUpEnabled(true);
            SupportActionBar.SetDisplayShowTitleEnabled(false);
            SupportActionBar.SetHomeButtonEnabled(true);
            SupportActionBar.SetHomeAsUpIndicator(Resource.Drawable.ic_menu);
            drawerLayout = FindViewById < DrawerLayout > (Resource.Id.drawer_layout);
            navigationView = FindViewById < NavigationView > (Resource.Id.nav_view);
        }
        public override bool OnOptionsItemSelected(IMenuItem item)
        {
            switch (item.ItemId)
            {
                case Android.Resource.Id.Home:
                    drawerLayout.OpenDrawer(Android.Support.V4.View.GravityCompat.Start);
                    return true;
            }
            return base.OnOptionsItemSelected(item);
        }
    }
