Visual Basic.NET was the product/marketing name for VisualBasicSeven? (a.k.a. VB7).
Despite Microsoft's dropping of the .NET moniker with VisualBasicEight, the community often uses the term VisualBasicDotNet to refer to all versions of VisualBasic that target the CommonLanguageRuntime.
The presence of the .NET moniker was due to the rampant use of the .NET brand across Microsoft (recall that Windows Server 2003 was named Windows Server .NET up until months before its release).
