Expose the core Live service in a cohesive and consistentway with .NET

Make it easy and natural for .NET developer to consumeLive Services

Have a symmetrical programming model

Authenticate as myself Use web authentication Web site has no access to my mesh

Authenticate as a user on my site Use delegated authentication User controls access to his mesh

Mesh enabled web sites authenticate same

as before


10/41

Use either local or cloud mesh

Local mesh is already authenticated

Cloud Mesh

App must get username and password

Use those credentials to authenticate to

the cloud


11/41

Local connection Local data cache

Use it when ofine capability required

Automatically syncs with the cloud

Cloud connection No local data cache

Use it when ofine capability not needed

LiveOperatingEnvironment class Connect your application to the LOE

Cloud Connection

Local Connection Uses default user credentials

Parameter Description

Orderby Sort the output by the values in the given element arg,where arg is a string.

Skip Skip the first arg results, where arg is a positive integer.

Take Return the next arg results, where arg is a positive

integer.Expand Prefetch the specified resources in arg, where arg is a

DataFeed Stores application information

Metadata and blobs

Receive update information

Has Replication and synchronization capabilities

A mesh object can have any number of data feeds

Remember to add a DataFeed to a newly createdMeshObject

// Read the file.

FileStream input = new FileStream(path + filename, FileMode.Open);

DataEntry dataEntry = df.DataEntries.Add(input, filename);

input.Close();

// Required to see user data on all devices/Live Desktop/Data Model Browser

dataEntry.Update();

// Make sure everyone is synchronized

df.SyncEntries.Synchronize();

df.Update();

DataEntry Data Entries and stored in a DataFeed

Lowest level of storage in a mesh object

What are they? Small domain specific language

Declarative way to interact with LOE

Logical equivalent of batched procedures

Why use them? Frees you from the lower level details of

the HTTP protocol

Improves eciency

Extend the Request processing pipelinewith custom business logic


30/41

Declarative modeling for

Control Flow Statements Sequence, Interleave, Conditional, CRUD

Data Flow Statements Bind statements

Run locally or on the server

Can run as triggers

Serialized as POX or JSON


31/41

SequenceStatement

Sequentially executes child statements

InterleaveStatement

Executes child statements in parallel ConditionalStatement

If Else execution

CRUD statements

Operate on resources


32/41

Server Side Execution

Script.RunAtServer(credentials)

Single HTTP request/response

Client Side (In Process) Execution

Script.Run(credentials)

Multiple HTTP requests/responses

Each statement generates request


33/41

Attach to a resource instance Pre and post logic on Create, Update

and Delete

Examples: Create a thumbnail after an image

resource is created

Remove a folder if the last child object isremoved
