I\'ve got a reference to System.Configuration - and ConfigurationSettings is found no problem - but the type or namespace \'ConfigurationMana
System.Configuration
ConfigurationSettings
ConfigurationMana
You need to use the System Configuration namespace, this must be included in two ways:
Right click the project and choose add reference, browse "Assemblies" and tick the System.Configuration assembly.
Include the namespace in code:
using System.Configuration;
