Maybe inside MS VB6 development has ceased, hence the ability to just say VB instead of VB.NET.
Plus, the ".NET" is going to soon be dropped from all of the MS products. Consumers get it. Everyone knows Visual Studio 2005 (or whatever) is a .NET-enabling IDE, everyone knows C# is C#.NET, ditto with J#, VB, etc.
That's my understanding anyways ![]()
