TcpClient connection

using TcpClient tcpClient = new(domain, port);

using TcpClient tcpClient = new(domain, port);

When I let this run on my local machine, it works fine. But on our server, I get System.Net.Internals.SocketExceptionFactory+ExtendedSocketException (10060). But only for some websites. I am using Port 443. Goal is to read the certificate with SslStream afterwards. When I tested it on the system of a colleague, he first had to run the program with Visual Studio, otherwise the exe produced the same errors for some websites as on the server. I have no idea what the issue could be.

Remove list element

AddTabGroupChildren(Config.KpiSelection.TabHierarchy.TabBase);
private void AddTabGroupChildren(List<XmlTabBase> members)
{
    members = members
        .OrderBy(p => p.Order)
        .ToList();

    var children = members.OfType<XmlTabGroup>().ToLookup(group => group.GroupId);
    foreach (var member in members.OfType<XmlTabGroup>().ToList())
    {
        member.TabBase.AddRange(new List<XmlTabGroup>(children[member.Order].ToList()));
        member.TabBase = member.TabBase.OrderBy(p => p.Order).ToList();
        if (member.GroupId != 0) members.RemoveAt(members.FindIndex(p => p.Order == member.Order));
    }
}

AddTabGroupChildren(Config.KpiSelection.TabHierarchy.TabBase);
private void AddTabGroupChildren(List<XmlTabBase> members)
{
    members = members
        .OrderBy(p => p.Order)
        .ToList();

    var children = members.OfType<XmlTabGroup>().ToLookup(group => group.GroupId);
    foreach (var member in members.OfType<XmlTabGroup>().ToList())
    {
        member.TabBase.AddRange(new List<XmlTabGroup>(children[member.Order].ToList()));
        member.TabBase = member.TabBase.OrderBy(p => p.Order).ToList();
        if (member.GroupId != 0) members.RemoveAt(members.FindIndex(p => p.Order == member.Order));
    }
}

I have a method which takes a flat list and generates a tree from it. At the end I remove the elements from the list which have been added as a child. This is the part which isn't working anymore and I don't understand why. Meaning when I look at members inside the method, the list at the end is correct, but the actual property still has the deleted elements. The added children are correct though.

XML Deserialization Null Exception

I have an XML element which usually looks like this

<LoginName><![CDATA[Name]]></LoginName>

<LoginName><![CDATA[Name]]></LoginName>

It is possible thought that someone deleted the whole cdata part and if that happened, when trying to deserialize it, I get a NullReferenceException.

public static XmlCDataSection ToCData(this string str)
{
    return new XmlDocument().CreateCDataSection(str);
}

[XmlIgnore] public string LoginName { get; set; }
[XmlElement("LoginName")]
public XmlCDataSection CDataLoginName
{
    get => LoginName.ToCData();
    set => LoginName = value.Value;
}

public static XmlCDataSection ToCData(this string str)
{
    return new XmlDocument().CreateCDataSection(str);
}

[XmlIgnore] public string LoginName { get; set; }
[XmlElement("LoginName")]
public XmlCDataSection CDataLoginName
{
    get => LoginName.ToCData();
    set => LoginName = value.Value;
}

How can I prevent this exception?

Set property based on another

    public class XmlTabColumnDefinition
    {
        [XmlIgnore] public string KeyValue { get; set; };
        [XmlElement("KeyValue")] public XmlKeyValue XmlKeyValue { get; set; }
    }
    public class XmlKeyValue
    {
        [XmlAttribute("ColumnName")] public string ColumnName { get; set; };
    }

    public class XmlTabColumnDefinition
    {
        [XmlIgnore] public string KeyValue { get; set; };
        [XmlElement("KeyValue")] public XmlKeyValue XmlKeyValue { get; set; }
    }
    public class XmlKeyValue
    {
        [XmlAttribute("ColumnName")] public string ColumnName { get; set; };
    }

How can I set ColumnName based on KeyValue? Meaning when I change KeyValue during runtime, ColumnName gets the same value and the other way around.
