In this article I describe how to extend an application functionality with F# scripting. Sometimes there is a need to extend existing application functionality with some custom behavior. If you don't want or can't go through application developing and building cycle every time you need additional feature, scripting can be a good solution. It allows to tailor your application for particular needs with minimal efforts.
The generic sort algorithm in .Net does not perform well on sorting strings. The reason for that is that it performs too many character comparisons while comparing strings.
There is a better algorithm described by Prof. Robert Sedgewick called multikey quicksort. Sedgewick is known for his developer friendly books on algorithms and his approach to empirically study algorithm performance. In the case of soring strings, Sedgewick provides a reference implementation of string sort in C:Sedgewick's Reference Implementation of Sorting Strings
His implementation is quite hard to understand but achieves excellent performance.
Basics of dataflow programming in F# and C# - CodeProjectArticle intoduces dataflow programming and provides basic implementations of dataflow variables in C# and F#
F# (pronounced F Sharp) is a multi-paradigm programming language, targeting the .NET Framework, that encompasses functional programming as well as imperative object-oriented programming disciplines. It is a variant of ML and is largely compatible with the OCaml implementation. F# was initially developed by Don Syme at Microsoft Research but is now being developed at Microsoft Developer Division and will be distributed as a fully supported language in the .NET Framework and Visual Studio as part of Visual Studio 2010.[2]
