How long before the line of business app in F# becomes the norm?

Question

With the recent news about F# being included with Visual Studio 2010, I got to thinking ... how soon before I see functional programming take hold in the usual "line of business app" space?

Answer 1

I would add the subjective tag to that one ;)

Personally, I don't think it will become the norm although it will be used in areas where it is well suited.

I don't think it will become the norm because it is best suited to certain layers of the application, but isn't well suited to other layers like UI.

Because of this, development of several layers will continue in C# or VB. From a company's perspective, even if F# is the better tool for one part of the application, they will tend to write it in C# or VB anyway to maintain consistency, because their programmers will be more adept in those languages and so that future hires will be easier to find.
