Live Framework .NET API Kit

• Dr Neil Roodyn
• 11am

 Agenda

• Key Take away
• Live Framework Overview
• Introducing the Live Framework API Kits
• Live Framework Kit for .NET
  • Overview
  • Key Concepts
  • Accessing Live
  • Managing application’s data
  • Sharing your data
  • Taking the application Offline

 Key Take away

• Live Framework allows you to integrate the power of the cloud in a cohesive and consistent way in your application
• Live Framework enables you to move to the next inflection point in the software industry
• .NET developers can use the Live Framework Client Libraries to build their application

 Overview

• A set of libraries which can be used to program using Live fx
• .NET, SilverLight and JavaScript Libraries available today
• Work on various platforms and programming languages

 Design Goals

• Expose the core Live service in a cohesive and consistent way with .NET
• Make it easy and natural for .NET developer to consume Live Services
• Have a symmetrical programming model

 Accessing Live

• LiveOperatingEnvironment class
  • Connect your application to the LiveOperatingEnvironment
    • Sync and async pattern available
    • Local or remote connection available
  • Main entry point to all Live Services
  • Optimize the access to resource at connection time

 Managing application’s data

• Mesh Object
  • Container of application defined metadata
  • Fundamental unit of extensibility, sharing and synchronisation
  • Can be replicated across a set of devices
  • Can be shared among a set of users and applications
  • Contains: Members, Mapping, News, DataFeeds, Activities
• DataFeed
  • Store application information: Metadata and blobs
  • Receive update information
  • Has Replication and synchronization capabilities
  • A mesh object can have any number of data feeds
  • An application may create/modify/delete feeds at any time
• DataEntry
  • Data Entries and stored in a DataFeed
  • Lowest level of storage in a mesh object

 Accessing Live

• Users control their data
• Delegated authorization via Live ID for web apps
• Apps work on behalf of user

 Navigating the Model

• It’s all about Collections!
• Meshobject.DataFeeds collection
• LiveItemCollection

 LiveItemCollection properties

• Title
• Entries
• IsLoaded
• LiveOperatingEnvironment
• SelfLink

 Querying Collections

• Collections are everywhere
• LINQing to Mesh data
• May want to filter, sort large data sets
• CreateQuery vs LINQ to Entries
  • Server side filtering
  • Client caching

 Sharing your data (Members)

• Represents a Windows Live ID’s membership in the MeshObject
• New members have to be invited to be part of the Resource
• Has a role based on the object: Full, Author, Writer, Reader

 Taking the application Offline

• Local End Point
  • Leverage the Symmetrical APIS
    • Same APIs are used in the local the remote end point
  • Change the target URL to be local
  • Mesh Service takes care of the data

 Summary

• Live Framework
  • Allows you to integrate the cloud in a cohesive and consistent way
  • Enables you to move to the next inflection point in the software industry
  • .NET developers can use the client Libraries to build their applications
• Start using it today, we want your feedback!
