2. The Plan
Better StructureMap StructureMap Advanced
software? Basics in Action Recipes

3. SOLID Principles
Single Responsibility
Open-Closed
Liskov Substitution
Interface Segregation
Dependency Inversion

4. SOLID

5. Why Use StructureMap?
• Achieve loose coupling
• Extensibility everywhere
Design • Improve testability
• SOLID!
• Mature: one of the oldest containers
• One of the fastest IoC containers
Features • Easy to learn Domain Specific Language
• Fully-loaded

6. Code!

7. Everyone Loves WebForms!

9. Service Locator
Design pattern which encapsulates the
processes involved in obtaining a service.
Requester Service Locator
Based on configuration, builds
Asks the locator for a up and returns the requested
particular service. service.

10. Model-View-Presenter
MVP is a user interface design pattern engineered to
improve the separation of concerns within an
application’s presentation layer.
Model View Presenter
Object that Interface that Acts upon the
defines the data displays the data. model, tells the
to be displayed. view what to do.

11. ASP.NET MVC DependencyResolver
http://mysite/Home/Index
Hey, give me the
HomeController!
ASP.NET MVC
Pipeline DependencyResolver
Here ya go!
Activator.CreateInstance(
typeof(HomeController));

12. ASP.NET MVC DependencyResolver
Hey, give me the
HomeController!
ASP.NET MVC
Pipeline SmDependencyResolver
Here ya go!
Container.GetInstance(
typeof(HomeController));

13. Decorator Pattern
Design pattern that allows behavior to
be added to an object at runtime.
Service Interface Decorated Type Decorator
Defines the public Wraps an instance
contract for the type
Base type that of the service
being extended. implements in interface to add
the interface. new behavior.

14. Decorator Pattern
SomeOtherDecorator
: IProductRepository
ProductLoggingDecorator
: IProductRepository
InMemoryProductRepository
: IProductRepository

15. Think compositionally!
“Favor composition over inheritance!”

16. We’ve only just begun!

17. To Recap
IoC rocks. Use it. Embrace it!
There’s a learning curve… but it’s worth it!
Makes it easier to create SOLID code.
Do it all with StructureMap!
