How to find and update a record in a recursive model?
This is what solved my issue: 
Xml.Document.Descendants().First(x => x == oldNode.XmlElement).ReplaceWith(newNode.XmlElement);
Xml.Document.Descendants().First(x => x == oldNode.XmlElement).ReplaceWith(newNode.XmlElement);

How to find and update a record in a recursive model?
I wrapped the XDocument stuff because I wanted flexibility on how to access the info: if I change my mind on which package or method to do something, I'll have one place to change it, not dozens

Depends on what your goals is for learning here. You could use C# in web dev, desktop apps, mobile apps, game dev, etc. Why did you start programming in C#?

How to find and update a record in a recursive model?

The NodeItem: 
public class NodeItem {
    public string Name { get; set; }
    public ObservableCollection<NodeItem> Children { get; set; }
    
    public NodeItem() {
        Name = "No name";
        Children = new();
    }
    public NodeItem(NModel node) {
        Name = node.Name;
        Children = new();
        foreach (var child in node.Children) { Children.Add(new NodeItem(child)); }
    }
}
public class NodeItem {
    public string Name { get; set; }
    public ObservableCollection<NodeItem> Children { get; set; }
    
    public NodeItem() {
        Name = "No name";
        Children = new();
    }
    public NodeItem(NModel node) {
        Name = node.Name;
        Children = new();
        foreach (var child in node.Children) { Children.Add(new NodeItem(child)); }
    }
}
