`IpHlpApi.GetExtendedUdpTable<IpHlpApi.MIB_UDP6TABLE_OWNER_PID>` Bug?

See original GitHub issue

Describe the bug I got a lot of large PID from UDP6 table.

It seems like a bug.

If I change to UDP table (IPv4) rather 6, and change AF_INET6 to AF_INET. There’s no any large PID, all in 5 digits.

What code is involved

static void PrintUdpV6() {
    using var table = IpHlpApi.GetExtendedUdpTable<IpHlpApi.MIB_UDP6TABLE_OWNER_PID>(IpHlpApi.UDP_TABLE_CLASS.UDP_TABLE_OWNER_PID,
                                                                                     Ws2_32.ADDRESS_FAMILY.AF_INET6);

    foreach (var row in table) {
        Console.WriteLine($"PID={row.dwOwningPid, 10}, EndPoint={new IPEndPoint(new IPAddress(row.ucLocalAddr), (ushort)IPAddress.NetworkToHostOrder((short)row.dwLocalPort))}");
    }
}

Expected behavior No large PID.
