Hi guy's. I have ported Flee to C#.
Updated grammatica from 1.5 alpha to 1.5 stable and modified it to work well with Flee.
I have ran all of the unit tests and they all pass
I have compared benchmark results from original flee to Flee# and Flee# parses expressions faster - most probably the grammatica update.
The project is in codeplex - http://fleesharp.codeplex.com/
