UnityEngine.Rendering.RenderPipelineManager is Missing in custom package?

How can I reference the RenderingPipelineManager in a custom package? The Rendering Pipeline Manager says its implemented in UnityEngine.CoreModule according to the Docs.

For example, the following won’t compile in a custom package.

using UnityEngine.Rendering;

public class MyClass
{
        private void OnEnable()
        {
            RenderPipelineManager.beginCameraRendering += HandleBeginCameraRendering;
        }

        private void OnDisable()
        {
            RenderPipelineManager.beginCameraRendering -= HandleBeginCameraRendering;
        }
}

Here is a screen shot of my packages Assembly Definition File. What I am I missing?

Bump

Can any one help me?

Still havn’t figured out. :confused:
