.core third part dll, app.config

Hi,

I am trying to convert a project into .net core. It uses a 3rd part dll which I cannot change. 

This 3rd part dll reads from the app.config file. 

I added an app.config to my .dt net core project so that the values the 3rd party dll can be read. This worked fine but the WCF config is causing me issues. I keep getting unrecgnised section error for the WCF config.

Is there a nuget package I can add to resolve this? Or is there another way I can work around this issue?

Thank you..
