                qr.Criteria.AddCondition(ce);

                // Exceute query

                EntityCollection caseCollection = service.RetrieveMultiple(qr);

                // update case count on contact - 

                Entity newlyCreatedContact =  service.Retrieve(contact.LogicalName, contactid, new ColumnSet("spousesname"));

                newlyCreatedContact["spousesname"] = caseCollection.Entities.Count.ToString();

                service.Update(newlyCreatedContact);

            }

        }

    }

}

Go ahead and check inside crm about the case count on the contact.

I hope this helps..
