ASP.NET
Its easy to make GUIDs in ASP.NET. Using Visual Basic or C#. Below is clean code to get GUIDs. When the .NET CLR creates GUIDs or UUIDs they are version 4 guids, where a '4' begins the third group of digits.
VB (Visual Basic)
Dim myGuid As String = Guid.NewGuid().ToString()C# (C Sharp)
string myGuid = Guid.NewGuid().ToString();
