Can't use appcompat controls in Xamarin project

Question

I've been trying to use AppCompat components in my Android Application but for some reason SetContentView method keeps throwing:

Android.Views.InflateException: Binary XML file line #1: Binary XML file line #1: Error inflating class android.support.design.widget.TextInputLayout

Stack trace of exception:

Activity is inheriting right class and is using right Theme(AFAIK)(I've tried using "@android:style/Theme.AppCompat" as well)

[Activity(Label = "AttendIT Mobile", MainLauncher = true, Icon = "@drawable/icon", Theme = "@style/Theme.AppCompat")]
public class LoginActivity : AppCompatActivity

Here are (relevant) project references and components.

Am i missing something? Any ideas?

EDIT

Here is my layout xml:

<?xml version="1.0" encoding="utf-8"?>

 </LinearLayout>

here is my packages.config

<?xml version="1.0" encoding="utf-8"?>

Code that is throwing exception:

private void Initialize()
{

    SetContentView(Resource.Layout.Login); //this method throws exception



    Button button = FindViewById<Button>(Resource.Id.LoginButton);
    button.Click += LoginButtonOnClick;

    TextView textView = FindViewById<TextView>(Resource.Id.Settings);
    textView.Click += SettingsOnClick;

    _loginLoader = new ProgressDialog(this);
    _loginLoader.SetCancelable(false);
    _loginLoader.SetMessage(Resources.GetString(Resource.String.LoginLoaderMessage));

    TimeSpan timeout = new TimeSpan(0, 0, 30);
    BasicHttpBinding binding = new BasicHttpBinding
    {
        Name = "basicHttpBinding",
        MaxBufferSize = 2147483647,
        MaxReceivedMessageSize = 2147483647,
        SendTimeout = timeout,
        OpenTimeout = timeout,
        ReceiveTimeout = timeout
    };      
    _client = new AttendITWCFServiceClient(binding, new EndpointAddress("http://192.168.1.104:55416/AttendITWCFService.svc"));
    _client.TryLoginCompleted += ClientOnTryLoginCompleted;
}

protected override void OnCreate(Bundle bundle)
{
    base.OnCreate(bundle);
    Initialize();
}

Packages Components

Show us your code for the respective call! Also have you tried cleaning your solution, deleting your bin/obj folders and rebuilding? — Jon Douglas
Sometimes cleaning and rebuilding won't do the trick, try closing VS and then clean rebuild your project. — JLONG
@JLONG tried everything you guys suggested, sadly nothing worked, added more stuff to answer that i believe might be of use. — Aleksandar
Can you please show your whole components and packages folder? I would like to check on something — JLONG
@JLONG Added. Just jeep in mind that this isn't only project in solution soo many of these packages aren't refrenced by it. — Aleksandar

The error is that:

java.lang.ClassNotFoundException: Didn't find class "android.support.design.widget.TextInputLayout"

Is a Android Support design library, on your case, You are missing that Library on your Package folder based on the screenshots of your project. Adding this Android Support Design Library would solve the problem. Install, close VS, clean rebuild and see of the error still persist. Cheers!
