Is visual basic still alive? I have not come across any recent certifications on it Whats so special about F#
Anything on F#
yes, it is alive and a first class citizen of .net as Microsoft told us. vb is a beginners language which should remain easy to learn, but will not have all new developments available in c#. see Microsoft blog comment https://blogs.msdn.microsoft.com/dotnet/2017/02/01/the-net-language-strategy/
regarding F# please also have a look at the linked Microsoft blog of my previous post. Beside that there was a conference of F# community in London last month.
