.NET Standard + Custom Renderer

Hi all,

I would like to ask if is it possible to have a custom renderer while using .NET Standard?
I am trying to upgrade my PCL to .NET Standard (due to the needs of some libraries of .net) however, seems like my custom renderers can't manage to find the reference to my .net standard library. So if it is possible, can I ask how can I do this? I appreciate all the help. Thanks!
