feature activation code using powershell does not pick appsettings values

This is a  very common scenario where , our deployment guides tend to be useless with automation just because features are activated well using UI in settings of site/site collection  , but fail using powershell.

Here is the solution to this :


using (SPWeb web = properties.Feature.Parent as SPWeb)
{
SPWebApplication webApp = web.Site.WebApplication;
Configuration config = WebConfigurationManager.OpenWebConfiguration("/", webApp.Name);
// App settings are retrieved this way
config.AppSettings.Settings["someAppSettingKey"].Value;

// Connection string settings are retrieved this way
config.ConnectionStrings.ConnectionStrings["someDBConnectionString"].ConnectionString
web.Site.Dispose();
}
