2. About me… • Chief Architect, Tellago, Inc • Microsoft advisor • Microsoft MVP • Oracle SOA ACE • Speaker, author • http://weblogs.asp.net/gsusx

3. Agenda • Why you should love dynamic languages • Dynamic languages and .NET • Demo, Demo, Demo, Demo

4. Dynamic languages?

5. Dynamic programming language is a term used broadly in computer science to describe a class of high-level programming languages that execute at runtime many common behaviors that other languages might perform during compilation, if at all. These behaviors could include extension of the program, by adding new code, by extending objects and definitions, or by modifying the type system, all during program execution.

6. Why should I care?

7. Modern enterprise applications leverage multiple programming languages (Polyglot programming)

8. Essence vs. Ceremony C# Ruby using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace ConsoleApplication3 { class Program { static void Main(string[] args) { Console.WriteLine("Hello Teched...."); } } } puts “Hello Teched….”

9. Uni-language apps == Multi-Framework apps

10. Meta-programming

11. Release mode

12. Dynamic languages on .NET?

13. Dynamic languages on .NET IronPython x.Foo IronRuby x.Foo C# x.Foo VB.NET x.Foo Others… $x{Foo}, … Dynamic Language Runtime GetMember Name=“Foo”, IgnoreCase=false ObjectBinder PythonBinder RubyBinder YourBinder COMBinder ?

15. Can dynamic languages improve enterprise .NET applications?

16. Absolutely….

17. Let’s take a look…

18. Four areas where dynamic languages can enhance .NET enterprise applications • Domain Specific Languages • Unit/Application Testing • Dynamic validations (aka rules-based validation) • Declarative configuration

19. Unit and Application Testing

20. I would like to…. • Write tests in a simple and understandable way • Efficiently implement application tests • Seamlessly integrate my tests into the development process

21. Implementing cool unit testing strategies with IronRuby DEMO

22. Domain Specific Languages

23. I would like to…. • Seamlessly design languages that model areas of knowledge of my application • Not have to become a languages expert • Fully integrate my DSLs into my .NET enterprise applications

24. Building Domain Specific Languages with IronRuby DEMO

25. Configuration Management

26. I would like to…. • Not have to deal with configuration madness • Have the mechanisms to efficiently represent configuration information • Not have to write lots of code to interpret the application configuration

27. Rich .NET Configuration Using IronRuby DEMO

28. Validation Logic

29. I would like to…. • Implement validation logic using declarative paradigms • Use domain specific validation languages • Extend the validation logic without impacting my application

30. Implementing Flexible Validation Rules Using IronRuby DEMO

31. Other scenarios for the use of .NET dynamic languages • Build management • Dependency injection • Management scripts • Workflow modeling

32. Conclusions • No language solves it all: great enterprise applications should be multi-language • No language paradigm solves it all: Great enterprise applications should benefit from both static and dynamic languages • IronPhyton and IronRuby can extend .NET enterprise applications in important areas (DSLs, Testing, Configuration, Validation….) • Start small, learn, improve…..
