.NET – Microsoft.SharePoint.Client – [..]\14\ISAPI
Silverlight – Microsoft.SharePoint.Client.Silverlight – [..]\14\LAYOUTS\ClientBin
ECMAScript – SP.js - [..]\LAYOUTS

8. Getting Started: 3 things to know
ClientContext is the central object
Before you read a property, you have to ask for it
All requests must be committed in a batch
clientContext = new ClientContext(“
clientContext.Load(list);
clientContext.ExecuteQuery();

9. High level handling of commands
Client Application
Server
Sequence of commands:
Client.svc
command 1;
command 2;
command 3;
Execute commands
in the batch:
XML
context.ExecuteQuery();
command 1;
command 2;
command 3;
JSON
Process results
Send results back

10. Client Object Model Limitations
You must handle synch/update semantics in code
No elevation of privilege capabilities
Requests are throttled
.net CLR has sync method; Silverlight CLR and Jscript are async
Limited subset of Server OM functionality
You only get what you ask for – nothing more (but sometimes less)

11. .Net CLR Client OM
Provides easy access from remote .NET clients to manipulate SharePoint data
Can be utilized from managed code – also from office clients etc.
Assemblies
Microsoft.SharePoint.Client.dll (281kb)
Microsoft.SharePoint.Client.Runtime.dll (145kb)
To Compare: Microsoft.SharePoint.dll – 15.3MB

13. Silverlight in SharePoint 2010
Native Silverlight web part allows for compilation and deployment of XAP-only solutions
One-click deployment from Visual Studio 2010
Web Parts can contain custom properties that are sent to Silverlight via the InitParams property
Abstracted visual design in Expression (make the designer do it!)

14. Silverlight CLR Client OM
Use the correct references:
C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions \14\TEMPLATE\LAYOUTS\ClientBin
Microsoft.SharePoint.Client.Silverlight
262KB
Microsoft.SharePoint.Client.Silverlight.Runtime
138KB

15. Silverlight Client OM

16. Building and Deploying Silverlight
Built in support in Visual Studio 2010
Redirect assembly output into Module
F5 deploy and debug experience
SharePoint WSP
Visual Studio builds WSP package on F5
Module
XAP
Deploy as Module

17. DEMO

18. JavaScript Client OM
Provides similar functionality to .NET/Silverlight COM from JavaScript/ECMAScript
Identical structure
Initialize Context -> Specify Items -> Load Objects -> Execute Query
Limited to current site context (no cross-site scripting)
Asynchronous (like Silverlight)
Be aware of syntax changes
get_web()
get_lists()
get_item()
