Unable to serialize the session state. Please note that non-serializable objects or MarshalByRef obj

[Mike Larkin]

I am attempting to store my session state via SQL Server...however, one
of my dataset is generating the following error:

Unable to serialize the session state. Please note that
non-serializable objects or MarshalByRef objects are not permitted when
session state mode is 'StateServer' or 'SQLServer'.

I have other datasets that serialize fine. What's the deal? Is there
a size limit? (The other datasets are smaller)

--Thanks!

most probably, one of the contents that you have in your dataset isn't
serializable. read the error message carefully for a clue
