[Ironpython-users] abstract class/not marked as serializable

[Avi Berko]

Hey,

We're trying to interface to a testing instrument (agilent VSA) that has a
factory function returning an abstract class, which implements some
remoting interfaces (MarshalByRef, etc...)

The instance is returned, but trying to call any method on it (including
__str__/__repr__) results in this error message:


Traceback (most recent call last):
  File "<string>", line 1, in <module>
SystemError: Type

Assembly 'System.Core, Version=4.0.0.0, Culture=neutral,
PublicKeyToken=b77a5c561934e089' is not marked as serializable.


What can I do to further analyze this problem?

Regards,
Avi
