F# isn't an OS. And it hasn't always been around, it's much newer than .NET.

And, so what? F# isn't C#. Why should a “C# dev” be expected to know F#.

F# is from MS and it's not exactly hidden by them. But why should a “.NET dev” be anything other than someone who has sufficient knowledge and proficiency with programming with the .NET framework, irrespective of whether it's all in VB.Net or whether they are a ployglot?
