Namespace error in .NET MAUI

[MScriptGit]

I keep getting this error when I try to use your package in a .NET MAUI app on Android:

Position 14:9
DataTemplateExtension: Could not
locate type for local: MainPage

This is my MainPage.xaml code:

<?xml version="1.0" encoding="utf-8"?>
<ContentPage
    xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
    
    xmlns:toolkit="http://schemas.microsoft.com/dotnet/2022/maui/toolkit"
    
    xmlns:local="clr-namespace:YTDownloader"
    
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
    x:Class="YTDownloader.MainPage">
    <ScrollView
        x:Name="scrollView"
        Orientation="Vertical"
        VerticalOptions="FillAndExpand">
        <VerticalStackLayout
            Padding="20,0"
            Spacing="10">
            <Label
                x:Name="lbl"
                Text="Character Counter"
                FontSize="Large"
                VerticalOptions="Center"
                HorizontalOptions="Center" />
            <Border
                Stroke="#00CC00"
                StrokeThickness="2"
                BackgroundColor="White"
                Padding="5">
                <Border.StrokeShape>
                    <RoundRectangle
                        CornerRadius="10.0" />
                </Border.StrokeShape>
                <Entry
                    x:Name="userInput"
                    Placeholder="Input here..."
                    PlaceholderColor="black"
                    TextColor="black" />
            </Border>
            <Button
                Text="Let's go!"
                Clicked="getEntry"
                BackgroundColor="#00CC00" />
            <Label
                x:Name="outputTxt" />
        </VerticalStackLayout>
    </ScrollView>
</ContentPage>

This is my MainPage.xaml.cs code:

using System;
using System.IO;
using Microsoft.Maui;
using Microsoft.Maui.Controls;
using YoutubeExplode;
using YoutubeExplode.Videos.Streams;

namespace YTDownloader
{
    public partial class MainPage : ContentPage
    {
        public MainPage()
        {
            InitializeComponent();

        }

        private async void getEntry(object sender, EventArgs e)
        {
            var youtube = new YoutubeClient();

            string videoUrl = userInput.Text;
            var streamManifest = await youtube.Videos.Streams.GetManifestAsync(videoUrl);

            // Get the highest bitrate audio-only stream
            var streamInfo = streamManifest.GetAudioOnlyStreams().GetWithHighestBitrate();

        }
    }
}

When I remove the content of the getEntry function, the error doesn't show.

Compilation gives no error, just the preview in my IDE.

I can't seem to resolve this, so please help me!
