I got the following warning
\'System.Configuration.ConfigurationSettings.AppSettings\' is obsolete: \'\"This method is obsolete, it has been replace
as its a warning i dont think it matters unless you have turned off a treat warnings as errors setting
add a reference to System.Configuration
all you have to do is to update to the latest code so where you used ConfigurationSettings.AppSettings[""] change to ConfigurationManager.AppSettings[""]
and this should work
