Tips on exposing F# to C#

Api and Methods

I suggest that you create one or more Api.fs files to expose F# code in a C# friendly way.

In this file:

• Define functions with PascalCase names. They will appear to C# as static methods.
• Functions should use tuple-style declarations (like C#) rather than F#-style params with spaces.

-- this SQL can be used to calculate the rank of a given user in a game, 
-- and the names/scores of those just above and below him.
-- This is useful in online games or citizen science projects where you 
-- just want to see the 'proximity' of other users around you, not the entire global rank

-- I want to find the rank and score for user_3, and other users 3 above and 3 below.
WITH global_rank AS (
  SELECT name, score, rank() OVER (ORDER BY score DESC) FROM scores
