Jean-Marc's DSL 101 Session
Domain-Specific Language Models are a powerful technique for embodying in a tool the abstractions specific to the software your business is building and guidance on how to use them with your own frameworks. In this session we will examine the domain-specific development pattern, and see how to build a simple graphical language from scratch. You will also learn how to make your graphical language domain-specific and finally how to add architectural guidance directly to the tool.
Code generation is an increasingly common technique in application development and forms a part of many Visual Studio extensions. With the addition of T4 to Visual Studio 2008, every developer has a powerful code generation engine available to them. In this session we'll look at patterns of usage of T4 and ways to structure your templates for large-scale reuse. We'll explore a sample that aids large scale code generation from DSL models and finally look at a community library which adds facilities to make the tricky problems of incremental code generation and reverse engineering from a DSL easier.
