- 4. • An externalpiece of functionality that may be added to an existing system by abiding by a contract pre-defined by that system. Plug-in (my definition)
- 8. • Split workacross natural boundaries • Incrementally create and deploy features • Deploy only new and updated modules • Don’t need source code for existing system
- 11. • Changes tocontracts are difficult to manage • Increased development time for small projects

- 25. • Single -Automatically choose one. • One of Many - Like Single, but give the user the choice. Think smart phone apps • Many Simultaneously – Using the composite pattern, many plug-ins are treated as one. Like browser plug-ins; they have the potential of overlapping
- 26. • Most IoCcontainers – Ninject (using ninject.extensions.conventions) – Castle.Windsor – Unity – StructureMap – MEF – Managed Extensibility Framework – MAF – Managed AddIn Framework – Many other IoC containers
- 28. Add Sales Tax toCalculation Toppings! More Toppings!
- 32. • Why notuse config files? Config files are for changing the data/data source. Plug-in architecture is for dropping in functionality • Deciding where to put plug-in points
- 33. • Recovering fromplug-in crashes • Dynamic loading and unloading at run time • Updating an application while it’s running

Editor's Notes
- #2 The icons use FontAwesome. If they appear to be missing, try installing the font from here: http://fortawesome.github.io/Font-Awesome/ As you may have guessed, this talk is about plug-in architectures in .NET.
- #4 Whenever you talk about plugin architectures, the canonical example is this: our electrical system. It’s a great example because you can plug things into it without affecting other devices plugged into the same system. It also represents a common standard that vendors can comply with.
- #5 My definition. Read it.
- #18 After this slide, jump into example 4-ConsoleEncrypter
- #23 After this slide, jump into example 5-CompositionRoot and 6-IoCContainer
- #34 Mention the real application that I put into production based on this sample code
