Is there anything specific that I should be careful with? What challenges may arise? Have I missed something important? I would welcome your feedback.

1. Use a data structure that offers fast lookups for keeping the visited URLs. Using sequential data structures like List(T) will be a poor choice. Try with HashSet(T) which uses hash tables internally and gives you lookups in constant time.
2. You don't really need to construct the link tree. A better approach would be to parse the links immediately after finding. I mean a producer/consumer queue would be good. A producer thread finds all the links and put it to a queue. Several consumer threads will be listening to the queue and processing each links. This way you can save the time you use for constructing link tree
3. Some pages will return a HTTP status code 301 or 302 which means Moved Permanently and 302 Found. Your code should be able to handle this and request again to the changed URL.
4. Define a depth level so that your application will not go into too depth when grabing URLs

XmlNodeList itemNodes = document.SelectNodes("/List/Item"); // assuming document is a XmlDocument instance.
foreach (XmlNode node in itemNodes)
{
    XmlAttribute nameAttribute = node.Attributes["Name"];
    XmlAttribute versionAttribute = node.Attributes["Version"];
    XmlAttribute filenameAttribute = node.Attributes["Filename"];

    // Adding to listview
    ListViewItem root = listViewObject.Items.Add(nameAttribute.Value);
    root.SubItems.Add(versionAttribute.Value);
    root.SubItems.Add(filenameAttribute.Value);
}

Is there a way I can combine my query to get all the attributes for item with a specific name. Like being able to get 1.0 from One

XmlNode itemNode = document.SelectSingleNode("/List/Item[@Name='One']");

public class MyControl : UserControl
