I'm dealing with some SOAP requests/response to Microsoft CRM, that I'm attempting to save off. The Response object I'm attempting to Serialize is the Microsoft.Xrm.Sdk.Metadata.OptionSetMetadataBase (https://msdn.microsoft.com/en-us/library/microsoft.xrm.sdk.metadata.optionsetmetadata.aspx). When I attempt to serialize my object using this extension method:
public static string Serialize(this IExtensibleDataObject obj, bool indent = false)
{
NetDataContractSerializer contractSerializer = new NetDataContractSerializer();
using (StringWriter stringWriter = new StringWriter((IFormatProvider) CultureInfo.InvariantCulture))
{
using (XmlTextWriter xmlTextWriter = new XmlTextWriter((TextWriter) stringWriter))
{
if (indent)
{
xmlTextWriter.Formatting = Formatting.Indented;
xmlTextWriter.Indentation = 2;
}
contractSerializer.WriteObject((XmlWriter) xmlTextWriter, (object) obj);
return stringWriter.ToString();
}
}
}
I get this error:
threw an exception of type 'System.Runtime.Serialization.InvalidDataContractException'
Data: {System.Collections.ListDictionaryInternal}
HResult: -2146233088
HelpLink: null

I would assume this is possible since I just retrieved this information via a SOAP request, and therefore it was just deserialized. Here is the Soap Response if it helps:

How do I get around this error?
Use DataContractSerializer instead - it will do the job. It can serialize types not marked with [DataContract] or [Serializable] attributes (default constructor is required + only public members will be serialized):
public static string Serialize(this IExtensibleDataObject obj, bool indent = false)
{
DataContractSerializer contractSerializer = new DataContractSerializer(obj.GetType());
using (StringWriter stringWriter = new StringWriter(CultureInfo.InvariantCulture))
{
using (XmlTextWriter xmlTextWriter = new XmlTextWriter(stringWriter))
{
if (indent)
{
xmlTextWriter.Formatting = Formatting.Indented;
xmlTextWriter.Indentation = 2;
}
contractSerializer.WriteObject(xmlTextWriter, obj);
return stringWriter.ToString();
}
}
}
