OpenTK - Useability of Accumulation Buffer

I'm trying to use accumulation buffer in OpenTK project to no avail.

I learned that in newer version of OpenGL it was removed so I was wondering if its usable in OpenTK and if yes then is it dependent on:

  1. Libary im using - im currently using OpenTK.Graphics.OpenGL.
  2. The version of OpenGL set in shaders for example:
#version 330

in vec3 vPosition;
in  vec3 vColor;
out vec4 color;
uniform mat4 modelview;

void
main()
{
    gl_Position = modelview * vec4(vPosition, 1.0);

    color = vec4( vColor, 1.0);
}

If any of this is at fault of not letting me use accum buffer then it will probably solve this question of mine too

If deprecated functionality is still available, depends on the OpenGL Context type.

If you use a compatibility profile OpenGL Context, then all the deprecated functionality, as a accumulation buffer, is still available, even in the most resent OpenGL version 4.6.
In a core profile OpenGL context, the deprecated functionality is removed.

By default OpenTK creates a compatibility profile OpenGL context.
