May 9, 2012Download as PPTX, PDF2 likes1,869 views

ASP.NET Web API is a framework that allows developers to build web APIs that embrace HTTP and help developers create RESTful services. It provides functionality for basic CRUD operations with HTTP methods, model binding, routing, validation, filtering, formatting responses, dependency injection, authorization, and OData queries. While not strictly REST itself, Web API can be used to build RESTful APIs and services as the web shifts from traditional sites to being powered by APIs.

Taking Web Applications OfflineMatt Casto

One of the main advantages of web applications is their ease of deployment. The same can't be said about desktop applications. However, desktop applications work without a network connection. While this used to be a deal breaker for web applications, recent developments in HTML 5 and browser plugins such as Flash and Silverlight allow developers to create web applications that work both online and offline. In this session, Matt will demonstrate how to create offline web applications in HTML 5, Silverlight and Air. Also, other factors for offline applications, such as client-side data storage, will be examined in detail.

REST and ASP.NET Web API (Tunisia)Jef Claes

REST is an architectural style for building distributed hypermedia systems based on HTTP. The core concepts of REST include resources identified by URIs, representations of those resources exchanged via standard HTTP methods like GET, PUT, POST, and DELETE. Effective REST APIs follow architectural values like performance, scalability, loose coupling, and consistency by making resources and relationships between them accessible over HTTP. ASP.NET Web API is a framework for building RESTful services on .NET. It allows creating HTTP-based services using controllers and attributes, supports content negotiation for XML and JSON, and includes features for error handling, message handlers, dependency injection, and testing.

C# ASP.NET WEB API APPLICATION DEVELOPMENTDr. Awase Khirni Syed

The document provides an introduction to ASP.NET Web API and discusses key concepts related to web services and HTTP including: 1. Web API allows exposing data and services to different devices by taking advantage of full HTTP features like URIs, headers, caching, and supporting various content formats like XML and JSON. 2. SOAP and HTTP are common protocols for implementing web services, with SOAP using HTTP and XML for serialization and HTTP serving as a more lightweight alternative supporting any content over the protocol. 3. Key HTTP concepts discussed include requests, responses, status codes, headers, and the stateless nature of the protocol, with HTTP providing a standard for communication between client and server applications.

ASP.NET Web API and HTTP FundamentalsIdo Flatow

ASP.NET Web API is the de facto framework for building HTTP-based services in the .NET ecosystem. With its WCF and MVC lineage, Web API brings to the table better architecture, easier configuration, increased testability, and as always, it's customizable from top to bottom. But to properly use Web API it is not enough to get familiar with its architecture and API, you also need to really understand what HTTP is all about. HTTP is the most common application layer protocol in the world, and yet, not many web developers are familiar with HTTP concepts such as of chunking, caching, and persisted connections. In this full-day tutorial, we will focus on designing and implementing HTTP-based services with ASP.NET Web API, and you will learn how to better use it to implement the features provided by HTTP.

Creating an Effective Mobile API Nick DeNardis

Your visitors interact with content, not with your website. Content consistency is crucial to a successful user experience. Re-publishing is one option but it’s an inside-out action that relies on the authority controlling where the information goes. An API frees your data and the responsibility to where it is published and accessed. Mobile is a major consumer for your API but not every API is setup to handle the mass of requests coming from those devices. Learn how to mobile devices consume API’s with limited or low bandwidth and how to to tailor your API to be as efficient and effective as possible. http://environmentsforhumans.com/2012/doteduguru-summit/

RESS: An Evolution of Responsive Web DesignDave Olsen

Responsive web design has become an important tool for front-end developers as they develop mobile-optimized solutions for clients. Browser-detection has been an important tool for server-side developers for the same task for much longer. Unfortunately, both techniques have certain limitations. I’ll show how both front-end and server-side developers can take advantage of the new technique called RESS (Responsive Web Design with Server Side Components) that aims to be combine the best of both worlds for delivering mobile-optimized content.

API Reliability GuideNick DeNardis

Creating a separate mobile website is a great idea until someone changes a data source on you. Your users don’t care if your LDAP is down or why they can’t pull up next the class schedule for next semester. In this session you will learn how to plan for the worst; network outages, slow response times and unorganized data. The mobile Web isn’t very useful without content and often that content is gathered from many sources that are out of the developers control. Gathering, protecting and organizing that data is the job of a smart developer and a successful mobile Web presence. This is accomplished by adding an API layer to everything you do. This session will walk you through the ins and outs of creating and maintaining a Web API that can extend far beyond your mobile presence.

DevOps NoteHirokazu MORIKAWA

This document discusses the concept of DevOps from multiple perspectives. It provides definitions and viewpoints on DevOps from several experts in the field. Key points made include that DevOps is a cultural and professional movement focused on collaboration between development and operations teams. It is not about any single tool or technology, but rather the collaborative culture and processes that arise from that culture. DevOps aims to break down silos between dev and ops.

Roslyn is the new open source .NET compiler platform from Microsoft that provides APIs to build code analysis tools. It treats the compiler as a service by exposing the compile pipeline. Developers can get started with Roslyn by downloading the SDK, installing Visual Studio extensions, and using project templates to build console apps, diagnostics, or code fixes that interface with the compiler at different stages. Existing projects like ScriptCS demonstrate early uses of Roslyn.

File -> new project to deploy in 10 minutes with TeamCity and Octopus DeployTomas Jansson

The document discusses setting up continuous deployment with TeamCity, Octopus Deploy, and PowerShell. TeamCity is used for continuous integration and Octopus Deploy is used to automate deployments. Octopus Deploy allows defining environments, roles, projects, and releases to deploy applications. PowerShell scripts can be used in Octopus Deploy to automate tasks like configuration, deployment, and cleanup. The overall goal is to have a fully automated continuous deployment process from building to testing to deploying applications.

Getting started with Elasticsearch and .NETTomas Jansson

This document provides an introduction to using Elasticsearch with .NET and the NEST client library. It demonstrates how to install and configure Elasticsearch on Windows, define mappings and index documents using NEST, perform various queries including fuzzy, highlighted, faceted queries, and add filters. NEST provides a strongly typed, fluent abstraction over Elasticsearch that allows querying and filtering Elasticsearch in a similar manner to Elasticsearch JSON queries. The document encourages attendees to view the demo code on GitHub for examples of indexing, querying, highlighting, faceting, and filtering documents using NEST.

Deployment taken seriously with Octopus Deploy and TeamCityTomas Jansson

Tomas Jansson presented on how to implement continuous deployment using Octopus Deploy, TeamCity, and PowerShell. The goal is to have an automated deployment process that builds, tests, and deploys code changes from version control to environments multiple times a day. TeamCity is used for continuous integration to build and run tests on code changes. Octopus Deploy provides a dashboard to manage deployments to environments like QA and production. It supports promotion of deployments between environments using a NuGet package. PowerShell scripts are run during the deployment process for tasks like configuration transformations. A demo showed how these tools can be configured to achieve continuous deployment.

State or intentTomas Jansson

1) Event sourcing stores the history of an application as a sequence of events, rather than storing the current application state. This allows testing by replaying events and integrating systems by subscribing to the stream of events. 2) In event sourcing, an event represents something that happened in the past, such as a customer moving or an order being placed. Applications can be tested by replaying events to ensure the correct outcome occurs. 3) Event sourcing avoids the impedance mismatch between objects and databases since events are part of the domain model. Applications can be rebuilt by replaying all events to reconstruct the state.

Editor's Notes

#3: Hej, jag heter Tomas
#6: Embracing – har en veldigt enkel programmeringsmodell for å komma åt og sette saker relatert til httpLightweight – inte så mycket statiskt kontext som vi er vana med fra WebFormsHelt enkelt et bra verktøy for å bygge Web APIs, det må ikke vara publika, du kan ha desse i stedet for WCF!!!Det var førr WCF Web API, men det passade bedre in i ASP.NET så nå er det der
#7: REST er noe som du må sørge for, bare fordi at du bruker et rammeverk som gjør det letter å bygge RESTful services så betyr det ikke at det blir det per automatik
#8: Level 0: Communication over HTTP, no use of resources. For example SOAPLevel 1: Introducing resources, but still carrying «verbs» in the messages, most of the «rest» services are hereLevel 2: Introducing verbsLevel 3: HATEOS (Hypermedia as the engine of application state), communicating state and possible steps
#11: Also some kind of reach.Other make money for you, if you have the right model
#12: Internet skalar, så borde også vi. Gjenom å bruke samme typ av arkitektur så øker vi våra chansar at kunna skalera braMåste koppla isär våra appliaktioner mer når saker hamnar i cloudet
#16: ASP.NET Web API finns demos og forklaringerDemo project kommer med magisk branching graf
