If you are looking for web frameworks, F# (a cousin of OCaml) is a better bet for you compared to OCaml and fits well with your current development environment.<p>F# has Suave.io which is more idiomatic along with asp.net mvc where you can fit F# into.<p>Freya for OWIN - RESTful development looks very nice too.<p>Canopy - for Web UI automation (DSL on selenium) is also an awesome tool.
