I used it for an internal app that's getting used by several of the top global pharma companies to solve an optimization problem. I would choose F# again in heartbeat for that sort of project: its expressiveness let me implement the core algorithm in just a few hundred lines of fast, readable code, and its seamless interface with Microsoft-world allowed me to to embed it in a standard "Enterprise" stack (a C#/WPF desktop app as well as an ASP .NET webapp).
