Flee# is a C# Port of Flee, an excellent expression parser and evaluator for the .NET framework(Written in VB.NET).
As the original Flee had no updates since 2009, I have decided to port it to C# and continue working on and improving this great library.
Flee# parses expressions and compiles them into IL code - resulting in very fast execution.
