Hello, Not sure if this issue has been raised as it is driving me nuts as another Mono/.Net runtime behavior differences.
I have a xml schema called FamilyTree2.xsd FamilyTree2.xsd <http://mono.1490590.n4.nabble.com/file/n4664552/FamilyTree2.xsd> . This has been validate in Eclipse's Xsd Editor. Then I have an instance document created using this schema and is called FamilyTree2SimplePerson.xml FamilyTree2SimplePerson.xml <http://mono.1490590.n4.nabble.com/file/n4664552/FamilyTree2SimplePerson.xml> I then use xsd.exe in Mono runtime 2.10.8.1 to generate a C# class from the schema. I then use the following code to deserialize the instance document into an person object: [Test] public void TestSimplePerson () { const String testFile = "FamilyTree2SimplePerson.xml"; String fileName = Path.Combine( Constants.DataFilesDirectory, testFile ); Assert.IsTrue( File.Exists( fileName ) ); LMar.Demo.person p = null; using( Stream input = File.OpenRead( fileName ) ) { XmlReaderSettings rs = new XmlReaderSettings(); rs.Schemas = new XmlSchemaSet(); rs.Schemas.Add( SchemaLoaders.FamilyTree2 ); rs.ValidationType = ValidationType.Schema; using( XmlReader reader = XmlReader.Create( input, rs ) ) { XmlSerializer ser = new XmlSerializer( typeof( LMar.Demo.person ) ); p = ser.Deserialize( reader ) as LMar.Demo.person; // XmlSchemaValiationException Assert.IsNotNull( p ); } } The schema is embedded into the assembly as embedded resource, The exception message is as follows: System.Xml.Schema.XmlSchemaValiationException: XmlSchema error: Attribute declaration was not found for name XML Line 6, Position 12. person is the base class of spouse which uses the xs:extension to define it in the schema. This error message points to the name for the spouse object. I believe this is a Mono & MS .Net incompatibility runtime error for the following reasons: 1) The instance document has been validated by Eclipse xsd/xml editor as well as online validator. In fact the instance document was created by Eclipse xml editor. 2) The same code ( the xsd generated code produced in .Net and Mono appear to be the same) shown above runs without error in MS .Net and retrieving all the values. Has anyone discovered this error? It is a simple usage of xs:extension, a very commonly used construct and should not cause any incompatibility. It is so disheartening to see superficial compatibility while beneath the surface so much differences. Is there a site that lists this kind of runtime incompatibility for people wanting to use Mono as serious tool? Every time I push Mono, I end up in a hole like this as I have encountered time and time again incompatibilities. Is there some quirky flags in the XmlReaderSettings to get this going in Mono? Thanks.
