Currently ExcludePropertyReferences is expecting DeclaringTypeName.DataContractName. Its more helpful if the type is fully qualified.

for example ; from below Json if we want to exclude :{"Officeaddress.houseaddress.city"}; .

Json:
//----------------------------------------------------------------------------
