From a recent Ars Technical article called “The future of Microsoft’s languages“, emphasis mine:
In spite of its name, the current Visual Basic is not the same language as the ancient Visual Basic 6, nor the Visual Basic for Applications used for macroing. The transition to .NET in 2002, with what was called, at the time, Visual Basic.NET, left developers familiar with those languages high and dry; although the new language was called Visual Basic, and looked a bit like Visual Basic, it was really just C# in disguise. There was no good migration path from old to new, and much of the simplicity of those older languages was forfeit.
This is a primary reason why so many Visual Basic developers choose Xojo after trying Microsoft Visual Basic (.NET): they don’t want “C# in disguise”.
