GetHostEntry on Windows 7 and .NET 3.5

By Perry

This is very useful feature as on Windows 7, it returns IPV4 and IPV6 address combine so you cannot use direct Dns.GetHostEntry(string.Empty).AddressList[0] method to get the IP address of specified machine.

You can simply use below code to get the IP address on specified machine but make sure that you target .NET is set to 3.5 and you have included System.Linq namespace.

IPAddress IP = Dns.GetHostEntry(fqdnHostName).AddressList.FirstOrDefault(addr => addr.AddressFamily.Equals(AddressFamily.InterNetwork));
