@naveenrevalino I also encountered this problem when I moved the project from .net core 2.2 to .net core 3.1, the solution was to install the missing library from nuget: System.Configuration.ConfigurationManager 4.7.0

Obrigado @nicolae-lupei
para mim funcionou adicionar o nuget System.Configuration.ConfigurationManager 4.7.0
