How do you programmatically setup the GLWpfControl?

I've been playing around with OpenTK and it's been great following along the examples/tutorials.

I really want to have the OpenGL render in a smaller portion of the Window so I've been trying to use GLWpfControl, and I want to do it without XAML but I can't get it running properly.

I've been trying to get it to run through dotnet CLI from a console template. Here is my code:

using System;
using System.Windows;
using OpenTK.Wpf;
using OpenTK.Graphics.OpenGL;
 
namespace Test {
    public class MyWindow : Window {
        
        [STAThread]
        public static void Main() {
            Application app = new Application();
            app.Run(new MyWindow());
        }

        public MyWindow() {
            GLWpfControl wpfControl = new GLWpfControl();
            wpfControl.Render += GLWpfOnRender;
    
            this.Content = wpfControl;

            var settings = new GLWpfControlSettings();
            wpfControl.Start(settings);
        }

        void GLWpfOnRender(TimeSpan delta) {
            Console.WriteLine(delta.TotalMilliseconds);
            GL.ClearColor(1.0f, 0.0f, 0.0f, 1.0f);
            GL.Clear(ClearBufferMask.ColorBufferBit); 
        }
    }
}

I'm expecting the control to be rendered with a red color, however it is black. It isn't black without the call to Start() and GLWpfOnRender is being called repeatedly after the call to Start().

Here is the .csproj file:

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net6.0-windows</TargetFramework>
    <RootNamespace>test_2</RootNamespace>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
    <UseWPF>true</UseWPF>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="OpenTK" Version="4.7.4" />
    <PackageReference Include="OpenTK.GLWpfControl" Version="4.2.2" />
  </ItemGroup>

</Project>

I think I'm missing something that might be done when you call InitializeComponent() while using XAML. I've been doing a lot of reading but I'm stumped.

here's a link to what I'm trying to replicate: https://github.com/opentk/GLWpfControl/tree/aefe945f65e4659bd6f9f82083a4a746c2fb03fc/src

Edit: I've inherited and overriden GLWpfControl, and able to use the DrawingContext to print text and do all sorts of stuff. So GL is not working with the control for whatever reason?
