I suggest that you create one or more Api.fs files to expose F# code in a C# friendly way.
In this file:
PascalCase names. They will appear to C# as static methods.

Option<_> is great for ROP (Railway Oriented Programming) but we get no info on what went wrong (the failure value is None which carries no info).
With the introduction F# 4.1 we got Result<_, _> a "smarter" Option<_> as it allows us to pass a failure value.
However, when one inspects the signature of Result.bind one sees a potential issue for ROP:
