The strange thing is that if I use your format: <add key="Key"
value="Value1,Value2" />
then GetValues() returns an array that contains only the first value
("Value1").

I also don't think it should work that way. NameValueCollection.Add() method
(unlike Set) _adds_ another value to an existing key if it already exists,
so why they implemented it differently in AppSettingReader?
