C# - Serialization Issue with Nested XML Elements Using XmlSerializer - Missing Data

I'm wondering if anyone has experience with I tried several approaches but none seem to work. I've been struggling with this for a few days now and could really use some help. I'm facing an issue while serializing an object to XML using the `XmlSerializer` class in C#. The object contains nested properties, and during serialization, some of the nested elements are missing from the resulting XML. Here's a simplified version of my classes: ```csharp public class Person { public string Name { get; set; } public Address Residence { get; set; } } public class Address { public string Street { get; set; } public string City { get; set; } } ``` When I attempt to serialize a `Person` object like this: ```csharp var person = new Person { Name = "John", Residence = new Address { Street = "123 Elm St", City = "Gotham" } }; var serializer = new XmlSerializer(typeof(Person)); using (var writer = new StringWriter()) { serializer.Serialize(writer, person); Console.WriteLine(writer.ToString()); } ``` The output XML is missing the `Residence` element completely. The resulting XML looks like this: ```xml <?xml version="1.0" encoding="utf-16"?> <Person> <Name>John</Name> </Person> ``` I have double-checked that the properties are set correctly, and I am using .NET 5.0. I even tried adding the `[XmlElement]` attribute to the `Residence` property: ```csharp [XmlElement] public Address Residence { get; set; } ``` However, it didn't help. I suspect it might be related to how I have defined the classes or some configuration issue with `XmlSerializer`. I've looked through the documentation but couldn't find anything that addresses this specific behavior. What can I do to ensure that the `Residence` element is included in the serialized output? For context: I'm using C# on Linux. Thanks in advance! What am I doing wrong? I'd be grateful for any help.
