PostSharp is the #1 pattern-aware extension to C# and VB. It allows developers to eradicate boilerplate by offloading repeating work from humans to machines. PostSharp contains ready-made implementations of the most common patterns and gives you the tools to build automation for your own patterns. Developers usually think in terms of design patterns, but with conventional programming languages, they end up writing boilerplate code. PostSharp extends the C# and VB languages with a notion of pattern. The result: shorter, cleaner code that’s easier to write and understand, contains fewer defects and is less expensive to maintain.
