  1. Modifying the WCF Service Factory and Making It Work For You Johan Danforth Eric Quist

  2. Agenda • Introduction to Software Factories • Web Services Software Factory • Modifying the Service Factory • Future of Software Factories

  3. Software Factories • Helps developers build a specific kind of application or software • Helps developers follow certain architectural guidelines and design patterns • Generates repetitive boilerplate code and lets you concentrate on more difficult parts • May also help with the software development process

  4. Software Factories • A typical Software Factory includes “stuff” like: • Architecture design guidance, patterns and walkthrough’s (written instructions) • Reference/sample implementations • Application blocks and reusable components • Guidance packages (automated wizards/tools) • Designers and DSLs

  5. Guidance Packages inVisual Studio • Contains ”recipes” (wizards and tools) which are integrated with the IDE to help you produce and generate code • Introduced by the Microsoft Patterns & Practices team • Completely modifiable – you can make it work exactly the way you want it to through code changes and configuration

  6. Web Services Software Factory • The WSSF (Service Factory) helps you build Enterprise Class Web Services • New solution templates • A number of wizards and guides • Guidance navigator • Integrated documentation • The WSSF ships with 4 guidance packages

  7. WSSF Solution Structure • Initial solution structure may seem overly complex at first glance • Made to support enterprise class services • Can easily be customized by the architect to fit the size and needs of the project

  8. Creating a web service Demo

  9. Modifying a Software Factory

  10. Modifying a Software Factory • Simple – changing the solution structure and project responsibilities • Moderate – changing or adding code templates (scripts and XML) • Hard – changing or adding recipes and wizards. Understanding of GAX needed.

  11. Moderate modification

  12. Modifying Service Factory Demo

  13. Sample Customizations We Did • Changed project types from Web Project to Web Application Project • Added references to external assemblies • Added custom web.config settings • Customized T4 templates (constructors, inheritance...) • Added custom recipes (Generate Data Contract from XSD...) • Customized existing recipes

  14. Current Releases of Service Factory • December 2006 • WCF and ASMX Web Services in C# • July 2006 • ASMX Web Services in VB.NET • Version 3 Alpha • Latest bits available on Codeplex • Release 15 November

  15. The Future of Software Factories • More work on models and designers (Domain Specific Language) • Better integration with existing tool-windows, editors, menu commands • Better integration with existing designers

  16. The Future of Service Factory • Future versions of Service Factory will have better support for • modeling services and contracts • authoring and changing the Service Factory • management, deployment and integration with TFS, service aggregation (services calling services) • service agent generation

  17. DSL Support in v3

  18. Software Factories Pros & Cons • Developers quickly up to speed • Things are (hopefully) built the same way and according to best practices • Higher production rate • Cargo Cult Coding? • Still waiting for good DSL and modeling support
