Unexpected Namespace Handling in XML Serialization with .NET Core - Issues with Custom Objects
I'm a bit lost with I've been struggling with this for a few days now and could really use some help. Quick question that's been bugging me - Hey everyone, I'm running into an issue that's driving me crazy. I'm facing an issue with XML serialization in .NET Core when trying to serialize a custom object that contains nested objects with different namespaces. I expect the output XML to reflect the appropriate namespaces for each object, but I'm seeing unexpected behavior where some elements are serialized without their namespaces. Here’s how I’ve set up my classes and the serialization process: ```csharp [XmlRoot(Namespace = "http://example.com/parent")] public class Parent { [XmlElement(Namespace = "http://example.com/child")] public Child ChildElement { get; set; } } [XmlRoot(Namespace = "http://example.com/child")] public class Child { public string Name { get; set; } } var parent = new Parent { ChildElement = new Child { Name = "Child Name" } }; var serializer = new XmlSerializer(typeof(Parent)); using (var writer = new StringWriter()) { serializer.Serialize(writer, parent); Console.WriteLine(writer.ToString()); } ``` Despite explicitly defining namespaces, the serialized XML output does not include the namespace for the `ChildElement`. Instead, I get the following output: ```xml <?xml version="1.0" encoding="utf-16"?> <Parent xmlns="http://example.com/parent"> <ChildElement> <Name>Child Name</Name> </ChildElement> </Parent> ``` I have already tried adding the `XmlElement` attribute on the `Child` class itself, but it did not help. Is there something I am missing in the configuration of namespaces, or is there another way to ensure that the namespaces are properly applied during serialization? I'm using .NET Core 3.1 for this project, so any insights or best practices specific to this version would be greatly appreciated! For context: I'm using C# on macOS. I'd really appreciate any guidance on this. I recently upgraded to C# LTS. I appreciate any insights! This is for a application running on Ubuntu 22.04. Could this be a known issue? My development environment is Ubuntu 20.04. Is there a simpler solution I'm overlooking?
