Error in the same namespace after an interface extension

Good morning guys, I have a little problem.

has a class called "SettingsPage" which extends "PageBase". PageBase "in turn extends both" IPageBase "and" Page ".

When in the graphics page of "SettingsPage" (Xaml) I specify that it is of type PageBase this gives me error.

The error says that "PageBase" does not exist in the same context but the name space is the same.

I put you below the classes competes

PageBase.cs

namespace EVS.Pages
{
    public class PageBase : Page, IPagebase
    {
        string IPagebase.Title => "No Title";
    }
    public interface IPagebase 
    {
        String Title { get; }
    }
}

SettingsPage.xaml.cs

namespace EVS.Pages
{
    public sealed partial class SettingsPage :  PageBase
    {
        string Title => "Settings";

        public SettingsPage()
        {
            this.InitializeComponent();
        }

    }
}

SettingsPage.xaml

<local:PageBase
    x:Class="EVS.Pages.SettingsPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:EVS.Pages"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d">

    <Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
        <TextBlock>Test</TextBlock>
    </Grid>
</local:PageBase>

thanks in advance, at your disposal for further clarification

This may happen because of some temporary files that are left out in the obj and bin folders of the project.

Click Clean Solution in the Build menu and then close Visual Studio and delete the obj and bin folders in the project folder.
