Answer 1

I am using VS 2017, I added 'using System.Configuration' directive and also follow the step to add a reference assembly to the project but IDE still complaint configuration manager does not exist, it turn out it is due to the .net core installed by Nuget just add a empty container. The package System.Configuration.Configurationmanager 4.5.0 need to be installed as well. Start Tools -> Nuget Package Manager -> Package Manager Console and type "Install-Package System.Configuration.ConfigurationManager -Version 4.5.0" and this resolve the problem. Refer below screenshot in Object Browser in VS2017
