4. AgendaIntroduçãoASP .NET: WebForms e MVCO que é MVC?Funcionamento do ASP .NET MVCWebForms: Vantagens e DesvantagensDemonstraçãoCriação de Controllers, Views e Rotas

5. Introdução: ASP .NET e WebFormsNão é a mesma coisa!WebForms, é um framework do ASP .NET - A plataforma para desenvolvimento de aplicações web

6. Agora temos o ASP .NET MVCQue é um outro framework para o ASP .NETE agora ficamos com duas opções:ASP .NET WebFormsASP .NET MVC

7. ASP .NET MVC: CaracterísticasTotal controlo do HTML geradoTotal controlo das URLs (Clean URLs)Permiteautomatizar testes na interface gráfica com facilidadeExtremamenteextensível

8. ASP .NET MVC: URLs simplificadasNo ASP .NET WebForms:/Produtos.aspx?Categoria={dF7504E0-4F80-1173-9A0C-0305482C3301}No ASP .NET MVC:/Produtos/Livros

9. O que é o ASP .NET MVC?Actualmente, é um framework instalado à parteNão vem com o Visual Studio 2008, nem com o .NET Framework 3.5. Nem mesmo no SP1 destesEstará incluído no Visual Studio 2010

10. O ASP .NET MVC incluiUm novo template de projecto Web

11. O ASP .NET MVC inclui1 (um) novo assembly e namespaceSystem.Web.MvcQue depende de outros assembliesSystem.Web.dll (2.0)System.Core (3.5)System.Web.Extensions (3.5)System.Web.Abstractions (3.5 SP1)System.Web.Routing (3.5 SP1)

12. OK, mas o que é esse MVC?MVC = Model-View-ControllerÉ um padrão de arquitecturaaplicacional,design patternPermiteseparar as responsabilidadesemumaaplicação

13. Separar responsabilidades?Sim. Porexemplo, a apresentação dos dados para o utilizadordeveserresponsabilidade de uma parte “X” da aplicação.Já a parte de obteros dados da base de dados, responsabilidade de uma parte “Y” da aplicação

14. Model-View-ControllerController(Entrada)View(Apresentação)Model(Lógica)

15. Funcionamento do ASP .NET MVCRequisição é redireccionada para o ControllerControllerRequest

16. Funcionamento do ASP .NET MVCController processa e forma um modelo de dadosControllerRequest

17. Funcionamento do ASP .NET MVCEsse modelo de dados é enviado para a ViewControllerRequestViewDataView

18. Funcionamento do ASP .NET MVCA View cria uma representação visual desses dadosControllerRequestViewDataView

19. Funcionamento do ASP .NET MVCE essa representação é enviada de volta para o navegadorControllerRequestViewDataViewResponse

20. EstruturaASP .NET MVCdemonstração

21. WebForms: VantagensDesenvolvimentorápido (RAD)Controlosque “trabalham” porvocêConceitosemelhante a desenvolverparaWindows Forms. Aproveitaconhecimentoprévio

22. WebForms: DesvantagensPoucocontrolosobre o HTML geradoMuitodifícilparaautomatizar testes naspáginasAbstração do funcionamento real das aplicações web (PostBacks, ViewState), quepodeinduzir a erros com facilidade

23. Um exemplo de como NÃO utilizar ViewStateASP .NETWebFormshttp://www.mulherconsciente.com.br
