InitailizeComponent() - from undefined to already exists

Hi all,

This morning i started a new Xamarin Forms project. At first i had the issue where InitializeComponent doesn't exist in this context appears.
I opened the xaml saved the doc and reopened the code behind. All worked surprisingly well.

After coming back from lunch i decided to deploy the app to a device again but during compilation i NOW get the error

The Xamarin Studio version of the error (of course i get a similar error in VS2013):
/Volumes/C/MPos Prototype/MobilePos/MPos/MPos/obj/Debug/MPos.Core.Views.Login.xaml.g.cs(22,22): Error CS0111: A member MPos.Core.Views.Login.InitializeComponent()' is already defined. Rename this member or use different parameter types (CS0111) (MPos.Core)

Any help would be welcomed

Thanks - Aiden

The code

//Login.xaml.g.cs  
public partial class Login : global::Xamarin.Forms.ContentPage {    
    [System.CodeDom.Compiler.GeneratedCodeAttribute("Xamarin.Forms.Build.Tasks.XamlG", "0.0.0.0")]
    private void InitializeComponent() {
        this.LoadFromXaml(typeof(Login));
    }
}

//login.xaml.cs
public partial class Login : ContentPage
{
    public Login()
    {
        InitializeComponent();
    }
}

//login.xaml
<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"

             x:Class="MPos.Core.Views.Login"
             Padding="30">

  <ContentPage.BindingContext>
    <viewmodels:LoginViewModel/>
  </ContentPage.BindingContext>

  <ContentPage.Resources>
    <ResourceDictionary>
      <Style TargetType="Button">    
        <Setter Property="BorderColor" Value="Gray" />
        <Setter Property="BorderWidth" Value="2" />
      </Style>
    </ResourceDictionary>
  </ContentPage.Resources>

      <Entry IsPassword="True"
             Placeholder="password"
             HorizontalOptions="Fill"
             VerticalOptions="Fill"/>
    </StackLayout>
    <StackLayout HorizontalOptions="FillAndExpand" VerticalOptions="Center" Spacing="10" Orientation="Horizontal">
      <Button Text="Cancel"
              Command="{Binding Cancel}"

              VerticalOptions="End"/>

      <Button Text="Login"
              Command="{Binding Login}"
              HorizontalOptions="FillAndExpand"
              VerticalOptions="Fill"/>
    </StackLayout>
  </StackLayout>
</ContentPage>
