There isn't one.
There is no single project which you can do with VB - you can do a huge variety of projects form a simple "guess the number" game to a global networked financial information system.
If you mean "what is the simplest project type to start with" then try creaing a Console Project - they are pretty basic, and all you need to get started is the two lines
Dim s As String = Console.ReadLine()
Console.WriteLine("You entered {0}", s)
