I have a third party WSDL file and XML Schema which I use to create the web service client. At large the WSDL looks as follows:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<wsdl:definitions xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"
xmlns:tns="http://sample.com/"

I used svcutil to generate classes from the WSDL file with the following command: svcutil Sample.wsdl Sample.xsd.
What I now want to do in my application is validate the object instances of these types before passing them on to a web service. I tried to do that by serializing such an instance using XmlSerializer and performing validation using the XmlReader:
TestRequestMessage msg = new TestRequestMessage();
msg.el1 = new ...
using (Stream stream = Assembly.GetExecutingAssembly().GetManifestResourceStream(schemaName))
{
XmlSchema schema = XmlSchema.Read(stream, SchemaValidationHandler);
XmlSchemaSet schemas = new XmlSchemaSet();
schemas.Add(schema);
using (MemoryStream memStream = new MemoryStream())
{
XmlSerializer ser = new XmlSerializer(typeof(RequestMessage));
ser.Serialize(memStream, msg);
memStream.Position = 0;
bool errors = false;
XmlReaderSettings settings = new XmlReaderSettings();
settings.Schemas = schemas;
settings.ValidationType = ValidationType.Schema;
settings.ValidationEventHandler += (o, e) => {
// act on validation error
};
using (XmlReader reader = XmlReader.Create(memStream, settings)) {
while (reader.Read()) {}
}
The problem now is that the validation does not fail, even if I don't set all required properties or set some invalid values according to schema restrictions.
Having a closer look at the generated classes I realized that the root elements are not in the namespace they should be.
Funny enough if I run xsd.exe Sample.xsd the generated classes are put in the correct namespace, i.e. the XmlRootAttribute is set with the correct name and namespace in contrast to the generated code using svcutil.
What I also tried to do is reuse the generated classes from the xsd.exe tool in my svcutil command using the reference switch. But this resulted in errors saying that the System.Runtime.dll could not be found.
However what I'd like to do is create the client code including the necessary type classes with svcutil. How can I do that correctly?
Any help is greatly appreciated.
