当前上下文错误中不存在InitializeComponent

Question

I'm getting this error on my Xamarin.Forms project whenever I try to create a Page with XAML+CS.

The namespace on the file corresponds:

And I've set the build action of the XAML Page to EmbeddedResource with the Custom Tool MSBuild:UpdateDesignTimeXaml .
I checked the .csproj and it sets correctly the build action:

  <ItemGroup>
    <EmbeddedResource Include="AppCore\Pages\SettingsPage.xaml">
      <Generator>MSBuild:UpdateDesignTimeXaml</Generator>
      <SubType>Designer</SubType>
    </EmbeddedResource>
  </ItemGroup>

And:

<Compile Include="AppCore\Pages\SettingsPage.xaml.cs">
<DependentUpon>SettingsPage.xaml</DependentUpon>
</Compile>

Cleaning the solution and deleting the obj/bin folders didn't help and neither reinstalling the packages via update-package -project Travlendar.Core -reinstall .

This is SettingsPage:

using Travlendar.Core.AppCore.ViewModels;
using Xamarin.Forms;

namespace Travlendar.Core.AppCore.Pages
{
    public partial class SettingsPage : ContentPage
    {
        public SettingsPage (INavigation navigation)
        {
            InitializeComponent ();
            BindingContext = new SettingsViewModel (this, navigation);
        }
    }
}

Found the solution, I had to delete the packages folder in the solution.
Then cleaning/re-building the solution and everything is working back.
