This project shows different OO Design Patterns and how I solve them in F#

Instead of directly creating functions with a string output i use a data-structure. Using a data-structure has many advantages. For example you need only one function to create proper HTML code with escaping and user rules. Instead of re-doing this, again and again.

You also can create structures that can be easily re-used.

• Decorator1.fsx - Example from Video - I would change nothing
• Decorator2.java - A "good" Java Example of Decorators
• Decorator2A.fsx - Solution with DU and plain functions
• Decorator2B.fsx - Solution with a common Record

• Factory1.fsx - PHP CarFactory example re-written in F#
• Factory2.fsx - Wikipedia IPerson example re-writte in F#
• Factory3.fsx - My own Example showing Partial Application
• Factory4.fsx - A Java Example with Shapes converted to F#

• Interpreter1.fsx - A simple Calculator

• Strategy1.cs - C# Example from Wikipedia
• Strategy1A.fsx - A more direct conversation of the C# version
• Strategy2B.fsx - An extended version that creates a data-structure

I started this project by watching a video, but then it turned into something different. Here are various resources I used to create this project.
