De-serialising XML into list yields empty list

Question

I've been trying to de serialise an XML file into a list, but whatever I do, the list ends up with a count of 0.

I've been searching Stack like I normally do, tried all kinds of things, but am at my wit's end. What's going wrong here?

My XML:

<?xml version="1.0" encoding="utf-8"?>
<lijst>
  <lijst_item>
    <id>1</id>
    <naam>NAME REDACTED</naam>
    <archived>false</archived>
  </lijst_item>
  <lijst_item>
    <id>2</id>
    <naam>NAME REDACTED</naam>
    <archived>false</archived>
  </lijst_item>
  <lijst_item>
    <id>3</id>
    <naam>NAME REDACTED</naam>
    <archived>false</archived>
  </lijst_item>
</lijst>

Lijst_item object:

[XmlType("Lijst_item")]
public class Lijst_item
{
    [XmlAttribute("id", DataType = "int")]
    public int ID { get; set; }

    [XmlElement("naam")]
    public string Name { get; set; }

    [XmlElement("archived", DataType ="boolean")]
    public bool isArchived { get; set; }

    public Lijst_item()
    {

    }

    public Lijst_item(int id, string name, bool archived)
    {
        this.ID = id;
        this.Name = name;
        this.isArchived = archived;
    }
}

Code used to de serialise:

using (StreamReader sr = new StreamReader(sFile))
{
    XmlSerializer deserializer = new XmlSerializer(typeof(List<Lijst_item>), new XmlRootAttribute("lijst"));
    var Test = (List<Lijst_item>)deserializer.Deserialize(sr);
}

Convert xml to List by Deserialize in c# Did not help me: Exactly what am I doing wrong? Is my XML malformed? My object? Can I for some reason not use a List?
