Hi,

I´m having a curious problem upgrading an app from .NET 1.1 to 2.0. I have
two processes comunicated using remoting. In 1.1 I used to pass a SortedList
object between them with no problem. But when I have migrated to 2.0, I get a
System.IndexOutOfRangeException with this stacktrace:

I suppose the problem is related with the serialization of the SortedList
class, but I haven´t found the reason of the different behaviour between 1.1
and 2.0.
If I test the remoting communication with a HashTable or ArrayList object,
there is no problem.

Any idea?
Thanks.
