has anyone been able to serialize IdentifyResults and/or it's collection

Hi,

I'm carrying out an IdentifyTask on the provider layer of my application. It returns a List<IdentifyResult> which needs to be passed to the SL side through my WCF service. I was looking this example,

http://blogs.esri.com/Dev/blogs/silverlightwpf/archive/2010/03/11/Sending-geometry-between-Silverlight-and-the-server-using-WCF.aspx

and MapPoint gets serialized just as easily. But IdentifyResult doesn't.

Help?

nvm. Along the way, I had been trying to serialize a map itself. How brave and stupid 😛

The error's a bit difficult to understand to be honest. I wont copy/paste the entire strack trace here, but here's how it goes

An ExceptionDetail, likely created by IncludeExceptionDetailInFaults=true, whose value is:
System.InvalidOperationException: An exception was thrown in a call to a WSDL export extension: System.ServiceModel.Description.DataContractSerializerOperationBehavior
contract: Silverlight.ESRIMapping:ESRIMappingService ----> System.Runtime.Serialization.InvalidDataContractException: Type 'System.Windows.Input.TouchDevice' cannot be serialized. Consider marking it with the DataContractAttribute attribute, and marking all of its members you want serialized with the DataMemberAttribute attribute.  If the type is a collection, consider marking it with the CollectionDataContractAttribute.  See the Microsoft .NET Framework documentation for other supported types.
   at System.Runtime.Serialization.DataContract.DataContractCriticalHelper.ThrowInvalidDataContractException(String message, Type type)
.....
.....

what you said does make sense. Currently, I'm trying to declare a serializable class where I have all the properties as in IdentifyResult, but skip the symbol because I don't need it here...
