API Scope• Subset of Microsoft.SharePoint• Scoped to SPSite/Site Collection and below– Site Columns– Content Types– List Definitions– List Instances– Web Parts– Workflows– Custom Actions– SharePoint Designer workflow activities– Event Receivers– Modules/Files


Unsupported Features

• Anything above the site collection• Access to External Code/Data• Creation of SPWeb/SPSite outside of context• SPSecurity• BCS (WCF service supported)

Solution Monitoring

• Protects Site Collection from resource intensive solutions

• Resource Points measure resource consumption

• Site Collection Quota limits resource consumption per day

• Absolute Limit limits resources consumed by a solution

SharePoint 2010 Approach• Developers build

custom solutions• Administrators leverage

resource monitors to check site collection usage

• Site collection owners deploy, activate and implement the customizations

Developer • Design, build and test

customizations

Administrator• Monitor customizations

Site Collection Owner• Activate and use

customizations• Install customizations


SANDBOXED SOLUTIONDEMO


Sandboxed Solution Summary• Easy Deployment Model – No coffee break• Limited functionality


Why Client Object Model?• More SharePoint Web services

is a major request• Client Object Model provides more complete API

instead of more services• Provides an abstraction layer to return results as

recognizable SharePoint objects• Consistent developer experience across platforms

(.NET, ECMAScript, Silverlight)


Supported Areas

• Site Collections and Sites• Lists, List Items, Views, and List Schemas• Files and Folders• Web, List, and List Item Property Bags• Web Parts• Security• Content Types• Site Templates and Site Collection Operations

.Net Client OM• Designed for use outside of SharePoint• Can be used with .Net 4.0 • Microsoft.SharePoint.Client

.Net ExampleClientContext clientContext = new ClientContext("http://server");

//Load methodclientContext.Load(clientContext.Web); clientContext.Load(clientContext.Web.Lists);

//LoadQuery methodvar q1 = from list in context.Web.Lists where list.Title != null select list; var r1 = context.LoadQuery(q1);


ECMAScript Client OM• ECMAScript Client OM is easily added to a

SharePoint ASPX page - reference:– _layouts/sp.js– Add this using <SharePoint:ScriptLink>

• All libraries crunched for performance– Use un-crunched *.debug.js by adding

<SharePoint:ScriptLink … ScriptMode=“Debug” />

• Method signatures can be different• Different data value types


Silverlight Client OM

• Silverlight Development Enabled by Client OM

• Can use Silverlight in separate ASPX page or in Web Part

• Can utilize Client OM in Silverlight to create SharePoint apps


Creating Silverlight Web Parts

• A Web Part can be a host for Silverlight• SharePoint ships with Silverlight web part• The web part can contain custom properties

that are sent to Silverlight via the InitParameters property

• The XAP file can be deployed to LAYOUTS and loaded at run time

• The Silverlight application can then make use of the Client OM.


JAVASCRIPT CLIENT OBJECT MODELDEMO


Client Object Model Summary

• 3 different versions• Need to load items to get data• Far easier than web services to get data


EXCHANGE INTEGRATION


EWS MA 1.1 Overview

• Managed API for developing applications that use Exchange Web Services

• Functional parity with EWS*• Makes EWS calls under the covers• Backwards compatible– Request versioning

new ExchangeService(ExchangeVersion.Exchange2010_SP1);

• Cloud compatible out of the box


Autodiscover

• Don’t hardcode EWS URL in your app!• Use Autodiscover to find most efficient Client

Access Server URL for a given mailbox– On-Premise• Global & distributed deployments

– Cloud based• Office 365• Outlook Live• Live@EDU


Autodiscover – Exchange Online

EXO Office 365

EWS MAApplication

EWS MA client contacts Autodiscoversevice

Autodiscover service returns URL for EWS

bindings

EWS MA client connects to Exchange Web Services

Firewall

EWS MA client executes callback to Validate URL

Redirection


Impersonation

• Application performs actions using another user’s– Identity– Permissions

• Exchange ApplicationImpersonation role needs to be granted to a user

• Service account is typically allowed to impersonate other accounts


OFFICE CLIENT/EXCHANGE DEMODEMO


Office Client/Exchange Summary

• Easy to program against exchange• Hybrid solutions to solve business problems• Call SharePoint from business systems



Authentication

• Claims + Federation + Multiple Authentication Providers• FedAuth cookie with HTTP Only Flag = WinInet.dll • Active vs. Passive
