XmlSerializer Deserialize don't works with new properties of complex type

Question

When I add a normal property of type string I have no problem to deserialize an old file. But If I add a more complex type like a Dictionary<,> it isn't working. I get an exception like "xml don't correspand to the given class" (sorry I only have the exception-message in german)

How can I get this to work without coding a fallback-mode to the old class?

public class Connection2Sap
{
    [XmlAttribute]
    public string Name { get; set; }
    public string Server { get; set; }
    public string Username { get; set; }
    public Connection2SapPassword Password { get; set; }
    public string SystemNumber { get; set; }
    public string Client { get; set; }
    public string Language { get; set; }
    public bool MockModeEnabled { get; set; }

    public Dictionary<string, string> AdditionalConfigParameters { get; set; } // NEW!

    public Connection2Sap()
    {
        Password = new Connection2SapPassword();
        AdditionalConfigParameters = new Dictionary<string, string>();
    }
}

XMLSerializer doesn't support Dictionary. Have a look at this question and the answers: http://stackoverflow.com/questions/2911514/why-doesnt-xmlserializer-support-dictionary — Gareth, Aug 02 '13 at 08:55
May be this [link](http://stackoverflow.com/questions/495647/serialize-class-containing-dictionary-member) can give you some pointer. — Nilesh, Aug 02 '13 at 09:00

A class implementing IDictionary is not serializable!

see Serialize Class containing Dictionary member
