Xamarin.Forms page not displaying xaml layout

I have a contentpage in c# along with a xaml file.

Page1.xaml.cs:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

using Xamarin.Forms;
using Xamarin.Forms.Xaml;

namespace CompanyName.Pages
{
    [XamlCompilation(XamlCompilationOptions.Compile)]
    public partial class Page1 : ContentPage
    {
        public Page1()
        {
            InitializeComponent();
        }
    }
}

Page1.xaml:

<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             x:Class="CompanyName.Pages.Page1">
    <ContentPage.Content>
        <StackLayout>
            <Label Text="Welcome to Xamarin.Forms!"
                VerticalOptions="CenterAndExpand" 
                HorizontalOptions="CenterAndExpand"
                   x:Name="test"
                   />
            <Button Text="Hello, World!" />
        </StackLayout>
    </ContentPage.Content>
</ContentPage>

This is a fairly large project so to isolate anything that could be causing issues, I set my MainPage to Page1.

App.xaml.cs:

using System;
using Xamarin.Forms;
using Xamarin.Forms.Xaml;
using System.Threading.Tasks;
using System.Linq;
using CompanyName.DataBases;
using CompanyName.Pages;
using CompanyName.Models;

namespace CompanyName
{
    public partial class App : Application
    {

   

        public static String OnDatabasesLoaded { get; } = "DatabasesLoaded";

        public static Boolean IsDatabasesLoaded { get; private set; }
       
        public App()
        {
            InitializeComponent();

          // The below line is my normal entry point
         //   MainPage = new NavigationPage(new MainPage()) { BarBackgroundColor = Color.FromHex("#2196f3"),BarTextColor=Color.White};

            MainPage = new NavigationPage(new Page1()); // I added this to see if Page1 would even work
        }

        

        protected async override void OnStart()
        {

            // Create the tabels

            /*
            ColorDatabase colorDatabase = await ColorDatabase.Instance();
            QuiltDatabase quiltDatabase = await QuiltDatabase.Instance();
            TextDatabase textDatabase = await TextDatabase.Instance();
            */

           


        }

        protected override void OnSleep()
        {
            // Handle when your app sleeps
        }

        protected override void OnResume()
        {
            // Handle when your app resumes
        }
    }


   
}

My problem is that my xaml file is not rendered. On both a physical device and the emulator, a blank screen appears (excluding the navigation bar at the top). Both the xaml and code behind are set as Embedded Resources. I am using Visual Studio 2022 with Xamarin.Forms 5.0.0.2478. I made a new project and I was able to create a new page and the layout displayed fine.

I haven't been able to see if this error happens on ios. All my testing has been on Android.

Thanks

"Both the xaml and code behind are set as Embedded Resources."
Why? code and xaml are not resource types. VS has to "compile" those files.

Let VS correctly insert them into your project:

  • Copy those files someplace safe outside the project.
  • Delete them from project.
  • Rt-click on project / Add New Item / Content Page, name "Page1".
  • Then open your originals in a text editor, so you can copy the text, paste them into the files created by VS.
