Make sure that the table you are returning has a schema  If not  then create a default schema  i e  add a column in that table

I found the actual solution   There is a problem in invoking your service from the client   check the following things     Make sure all  datacontract    datamember  attribute are placed properly  i e  make sure WCF is error free  The WCF client  either web config or any window app config  make sure config entries are properly pointing to the right ones   binding info  url of the service  etc  etc    Then above problem   tempuri issue is resolved   it has nothing to do with namespace   though you are sure you lived with default    Hope it saves your  number of hours

Are you sure your web service is deployed correctly to the enviornment that is NOT working   Looks like the type is out of date

In our case the problem was that we change the default root namespace name      This is the Project Configuration screen  We finally decided to back to the original name and the problem was solved   The problem actually was the dots in the Root namespace  With two dots  Name Child Child  it doesnt work  But with one  Name ChidChild  works

I have a solution for this but not sure on the reason why this would be different from one environment to the other - although one big difference between the two environments is WSS svc pack 1 was installed on the environment where the error was occurring   To fix this issue I got a good clue from this link - http   silverlight net forums t 22787 aspx ie to  please check the Xml Schema of your service  and  the sequence in the schema is sorted alphabetically   Looking at the wsdl generated I noticed that for the serialized class that was causing the error  the properties of this class were not visible in the wsdl   The Definition of the class had private setters for most of the properties  but not for CustomFields property ie     Serializable  public class FileMetaDataDto               a constructor      etc and several other properties edited for brevity             public int Id   get  private set        public string Version   get  private set        public List lt MetaDataValueDto gt  CustomFields   get  set         On removing private from the setter and redeploying the service then looking at the wsdl again  these properties were now visible  and the original error was fixed   So the wsdl before update was  -  lt s complexType name  ArrayOfFileMetaDataDto  gt  -  lt s sequence gt     lt s element minOccurs  0  maxOccurs  unbounded  name  FileMetaDataDto  nillable  true  type  tns FileMetaDataDto    gt      lt  s sequence gt     lt  s complexType gt  -  lt s complexType name  FileMetaDataDto  gt  -  lt s sequence gt     lt s element minOccurs  0  maxOccurs  1  name  CustomFields  type  tns ArrayOfMetaDataValueDto    gt      lt  s sequence gt     lt  s complexType gt    The wsdl after update was  -  lt s complexType name  ArrayOfFileMetaDataDto  gt  -  lt s sequence gt     lt s element minOccurs  0  maxOccurs  unbounded  name  FileMetaDataDto  nillable  true  type  tns FileMetaDataDto    gt      lt  s sequence gt     lt  s complexType gt  -  lt s complexType name  FileMetaDataDto  gt  -  lt s sequence gt     lt s element minOccurs  1  maxOccurs  1  name  Id  type  s int    gt      lt s element minOccurs  0  maxOccurs  1  name  Name  type  s string    gt      lt s element minOccurs  0  maxOccurs  1  name  Title  type  s string    gt      lt s element minOccurs  0  maxOccurs  1  name  ContentType  type  s string    gt      lt s element minOccurs  0  maxOccurs  1  name  Icon  type  s string    gt      lt s element minOccurs  0  maxOccurs  1  name  ModifiedBy  type  s string    gt      lt s element minOccurs  1  maxOccurs  1  name  ModifiedDateTime  type  s dateTime    gt      lt s element minOccurs  1  maxOccurs  1  name  FileSizeBytes  type  s int    gt      lt s element minOccurs  0  maxOccurs  1  name  Url  type  s string    gt      lt s element minOccurs  0  maxOccurs  1  name  RelativeFolderPath  type  s string    gt      lt s element minOccurs  0  maxOccurs  1  name  DisplayVersion  type  s string    gt      lt s element minOccurs  0  maxOccurs  1  name  Version  type  s string    gt      lt s element minOccurs  0  maxOccurs  1  name  CustomFields  type  tns ArrayOfMetaDataValueDto    gt      lt s element minOccurs  0  maxOccurs  1  name  CheckoutBy  type  s string    gt      lt  s sequence gt     lt  s complexType gt

Do you have this namespace setup   You will have to ensure that this namespace matches the message namespace   If you can update your question with the xml input and possibly your data object that would be helpful    DataContract Namespace    http   CompanyName com au ProjectName    public class CustomFields

This is happening because the web-service relies on using XmlSerializer to convert the wsdl among other things to XML  which doesn t support mixed-mode properties  like these   public string strThing   get  private set      See  http   msdn microsoft com en-us library ms978420 aspx  More information  http   www geekscrapbook com 2010 03 06 serializing-data-with-system-runtime-serialization-datacontractserializer
