This document provides an overview and agenda for a presentation on building modern web applications with ASP.NET 5. The presentation covers topics like middleware, dependency injection, configuration, and view components. It includes demos of adding middleware, injecting dependencies, loading configuration from different sources, and using a view component. The goal is to introduce key concepts in ASP.NET 5 and show examples of working with middleware, dependency injection, configuration, and view components.

- 5. Agenda • Introduction • Middleware • Dependency Injection • Configuration • View Component • Lots of Demos • Conclusion 5
- 6. ASP.NET 5 10
- 8. Where is my HTTP Pipeline?
- 9. HTTP Pipeline HTTPModule 1 HTTPModule 2 HTTPModule 3 HTTPModule n HTTP Handler Request Response . . . 1 • Application_BeginRequest 2 • Application_AuthenticateRequest 3 • Application_AuthorizeRequest 7 • Application_PreRequestHandlerExecute 8 •Handler executes the request 9 •Application_PostRequestHandlerExecute 10 • Application_ReleaseRequestCache 11 • Application_UpdateRequestCache 12 • Application_EndRequest 1 • Application_BeginRequest 2 • Application_AuthenticateRequest 3 • Application_AuthorizeRequest
- 10. Middleware Pass through components that form a pipeline between a server and application to inspect, route, or modify request and response messages for a specific purpose. It’s same as a HTTP Module
- 11. Middleware Processes the HTTPContext items HTTPContext _next _next(httpcontext) _next(httpcontext)
- 12. Middleware Chaining Middleware1 Middleware2 Middleware3 Middleware4 Request Response 25
- 13. Let’s add some middlewares 35 Demo
- 15. How? • Startup class has one more method to register the dependencies. • These can be injected via property or constructor in any component. • ConfigureServices – Instance – Transient – Scoped – Singleton
- 16. Time to inject dependencies Demo 45 Demo
- 17. Where are Config files
- 18. Where are configuration files Earlier • *.config files at different levels • System.Configuration namespace to play with config files Now • These are not supported • Lightweight that works on Cloud • Different configuration in different environment
- 19. What we get • Light-weight • Should work same everywhere, cloud optimized • Have different configuration instance for different sub system like Identity, MVC, Razor • Able to load configuration from diff sources • Instantiated and Initialized in application itself • Supports – Json, xml,ini, environment variables, command line
- 20. Add entry in Config Demo 55 Demo
- 21. View Component • A simple replacement for child actions • Can be used instead Partial Views as well • Easy separation of concerns and testable • Provide the power of asynchrony • Contains two parts – A class that inherits from ViewComponent – A razor view which calls VC method
