OpenTK NotImplementedException tutorial

Question

I am trying to create a Windows Form with an openGL canvas on it, or rather a GLControl so I'm using openTK. Because I'm still new to it, I have decided to try out the following tutorial

It took me a while to find a version which allowed me to add a GLControl to the visual studio toolbox; many different versions gave me an error ("There are no components in C:...\OpenTK.GLControl.dll that can be placed on the toolbox)

Using the current version from the official github finally got that part working for me.

private void glControl1_Resize(object sender, EventArgs e)
{
   int w = glControl1.Width;
   int h = glControl1.Height;
   glControl1.MakeCurrent();
   GL.MatrixMode(MatrixMode.Projection);
   GL.LoadIdentity();
   GL.ClearColor(Color.SkyBlue);
   GL.Ortho(-w / 2, w / 2, -h / 2, h / 2, -1, 1);
   GL.Viewport(0, 0, w, h);
   GL.End();
   glControl1.SwapBuffers();
}

however when I implement this from the tutorial inside my form and assign that method to the GLControl in the designer I get a NotImplementedException. The same goes for the glControl1_Paint (and glControl1_Load) I have also tried to assign these methods to the form itself instead but it yielded the same error.

The output I get from running the application is

Does anyone happen to know what's causing this problem and how I should solve it? Thank you in advance!

Using the pre-release versions I managed get the GLControl into my toolbox by using the .dll copy inside the bin\debug instead of using the one in the paket folder that's included to the solution upon using NuGet.

Note: I've copied the OpenTK.dll, OpenTK.dll.Config, and OpenTK.GLControl.dll to the debug folder

links to the pre-releases:

OpenTK.GLControl

OpenTK

Installing openTK.GLControl.Next will automatically install OpenTK.Next. Since I could not find the answer very easily I'm posting it here instead of deleting this question.
