After Winter release we encountered an issue for our .Net integration related to Soap API schema WSDL.
It is a known issue with the XML serialization class from .NET Framework all versions. The XMLSerializer code generation component cannot handle the XSD definitions that have only one element and the occurrence of the element is unbounded.
This is the case with the newly introduced classes ListViewRecord and ListViewRecordColumn from Salesforce API 32.0.
We had to manually modify the schema and altered the constructors for those 2 classes mentioned above by adding an extra dummy attribute.
This way the XMLSerializer code generator will use the proper XmlSerialization attributes for the constructor.

There should be a way to update WSDL from Salesforce to support .Net integration without manually update

Thank you!
