I cant deploy a VS-2017 app(Android and IOS) to an iphone

Question

I am trying to deploy an app to a iphone but it give the next warning:

MTOUCH : warning MT0136: Cannot find the assembly 'System.Configuration, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a

and then this error:

MTOUCH : error MT2101: Can't resolve the reference 'System.Configuration.ConfigurationException', referenced from the method 'System.Void System.Configuration.ConfigurationErrorsException::.ctor(System.String)' in 'System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089

• I can run the app in simulator but no in a real device..

• I read that I have to add System.Configuration assembly but it doesn't appears in the options

Usually after you right click "references" in your project, "add references" and search for "configuration" it at the top right under the "Assemblies" tab you should find a reference called "System.Configuration" that you can add to your project.
