AppConfig values in the .net core

Hi,

I am using .net core 2.0 and referred a dll (application developed in VS 2008).

The dll contains appconfig appsettings values. 

Since .NET core is the parent project it is not getting the values from VS 2008 config file. 

Where I should assign the appsettings value in the .net core 2.0 project.

Thanks.
