Live Framework .NET KitDesign goals

Expose the core Live Services in a cohesive and consistent way

Make it easy and natural for .NET developers to consume Live Services

Offer a symmetrical programming model between client and server

Live Framework .NET KitAccessing Live Data

LiveOperatingEnvironment class Main entry point to all the Live Services Connect your application to the runtime endpoint

Sync and asynchronous patterns available Local or remote connections available

Set pre-fetch policy at connect time

foreach (Contact contact in loe.Contacts.Entries){ Console.WriteLine(contact.Resource.DisplayName);}

public static void Connect (NetworkCredentials creds){ Uri uri = new Uri(“https://user-ctp.windows.net”); LiveOperatingEnvironment loe = new LiveOperatingEnvironment(); loe.Connect(creds)}

Live Framework .NET Kit Accessing Live Data

Users control their data Rich applications work on behalf of users Web applications require

delegated authentication Mesh enabled web apps are sandboxed

Cloud LOE APIs

User

(1) Visits

(2) Consent Request to Access a Live FolderThird Party

Website/Application

Live Desktop

(4) Del Auth Token

(3) Views Request and Gives Consent

(5) API call with Del Auth Token

Live Framework .NET KitManaging application data

Mesh Object Container of application defined data Fundamental unit of extensibility, sync and sharing Can be replicated across a set of devices Can be shared among a set of users

and applications Contains:

DataFeeds , Members, Mappings, News, Activities

MeshObject pokerObj = new MeshObject("PokerInfo");PokerChip chip = new PokerChip();pokerObj.Resource.SetUserData<PokerChip>(chip);loe.Mesh.MeshObjects.Add(ref pokerObj); public class PokerChip{ public int NumberOfChips { get; internal set; } }

Live Framework .NET KitManaging application data

DataFeed Stores application information

Metadata and blobs Has replication and sync capabilities An application may CRUD feeds at any time Receives update information A mesh object can have

any number of data feeds

DataFeed feed = new DataFeed();feed.Resource.Type = “LiveMeshFolder”;feed.Resource.HandlerType = “FileSystem”; meshObject.DataFeeds.Add(ref feed);

Creating Mesh Board

demo

Live Framework .NET KitSharing data

Members Represents a Live ID’s

membership in the MeshObject New members have to be

invited to be part of the Resource Has a role based within the object

Full, Writer, Reader

foreach (Member member in meshObject.Members.Entries){ Console.WriteLine(member.Resource.Title); Console.WriteLine(member.Resource.InvitationAccepted); Console.WriteLine(member.Resource.Role);}

Live Framework .NET KitSharing data

FeedSync Synchronization via RSS and Atom feeds Lightweight and extensible Supports multi-master Delivers same result at all endpoints Protocol independent Preserves conflicting data Diverse implementations encouraged Creative Commons Microsoft Open Specification Promise

Inviting Users

demo

Live Framework .NET KitTaking applications offline

Local endpoint Leverage the Symmetrical APIS

Same APIs are used in the local and cloud end point Change the target URL to be local Mesh Service takes care of the

data synchronization

public static void Connect (NetworkCredentials creds){ LiveOperatingEnvironment loe = new LiveOperatingEnvironment(); //loe.Connect(creds) loe.ConnectLocal();}

Rich Client Application
