Design Pattern Automation  Gael Fraiteur

Design patterns are now universally accepted and significantly improved the way we design software. However, they had relatively little impact on how we implement it. Except rare exception like the 'using' or 'lock' keywords, most patterns must still be implemented by hand, resulting in large quantities of boilerplate code that must be validated by peer review. However, smarter compilers and development tools could do a better job by automatically implementing part of the pattern and automatically validating the other part that has been implemented manually. This talk advocates for a better integration of pattern thinking in the whole development cycle. It discusses how design pattern automation is possible today in .NET using PostSharp, FxCop, and Nemerle.


  • Patterns in architecture and methodology
  • The feedback loop: ex-post patterns and refactoring
  • Well-written patterns can be partially automated
  • Disposable Object: a pattern with framework/compiler support
  • Observable Object: a ready-made implementation with PostSharp
  • Validating pattern implementation using FxCop
  • Metaprogramming: dynamic languages, scala macros, Nemerle
  • Automating design pattern implementation/validation using PostSharp

(Dauer 75min, Vortrag in englischer Sprache)
