If you use XML serialization only public properties are serialized and since forms tend not to have a large public interface it should be easy to keep the XML pretty small.

Viv,

thank you.

Which is better style: use parameterized constructor for forms or not to use ?
I think I must use only constructurs without parameters. I can read parameters from isolated storage also and then after yourt code use

lf.Configure( param1, param2 )
