Creating a Rich Business Application with the Managed Client Object Models in SharePoint 2010 (MDV01) – my notes

SharePoint Connections 2010, Den Haag, 28 September 2010

Session: Creating a Rich Business Application with the Managed Client Object Models in SharePoint 2010  (MDV01)

Speaker: Andrew Connell (http://www.andreconnell.com/blog)

• This session contained mostly things that apply to SharePoint 2010 but there were also remarks about SharePoint 2007
• Important points
  • Overview of building Rich Internet Applications (RIA)
  • Options we have in SharePoint 2007
  • Options we have in SharePoint 2010
• Riche Internet Applications (RIA)
  • As a definition, RIA engages client-side solutions, meaning AJAX, Flash, Silverlight
  • In SharePoint 2007 you might need extra setup and config
  • In SharePoint 2010 it’s out of the box + extra connection points from client applications.
  • Security trimming is present in both versions -> nothing to do for the developers
• Option we have for RIA In SharePoint 2007:
  • ASP.NET 2.0 (. ASMX web services)
  • WCF (.SVC) technically not supported
  • Silverlights v3 which requires ASP.NET 3.5 and a lot of edits in web.config
• Options we have for RIA in SharePoint 2010
  • Better consume & create web services (ASP.NET & WCF)
  • Client Object Model
    • A lot more interaction is possible with the site collection
    • Extends the SharePoint object model to Silverlight
    • Enables developers to work with familiar objects rather then web services
    • It’s centered on the ClientContext  – handles communication with SharePoint sites.
    • Sends commands to SharePoint (ExecuteQueryAsync(success,fail))
    • Using it requires 2 references:
      • Microsoft.SharePoint.Client.Silverlight.dll; (this includes .NET Client OM API’s
      • Microsoft.SharePoint.Client.Silverlight.Runtime.dll (does all the communication to SHAREPOINT server back and forth); (to be found in […]/14/templates/layouts/ClientBin/)
      • LINQ is only working on servers side…on client side you will need CAML query!..CAML is dead..long live CAML J
      • Works only using async communication
  • OData/WCF Data Services / RESTful services
    • Very easy to read/write data to lists and sites.
    • It does not allow changes of structure, permissions, or navigation like within the client model.
    • OData is an open protocol founded on REST principals
    • WCF Data Services is the Microsoft implementation of OData open protocol
    • Does not work out of the box!! J To make it work you need WCF Data Service Update for .NET 3.5 SP1
    • OBS: Dataaccesspolicy.xml defines who can call which service (normally found in the root of the Inet application)
  • Sandbox Solutions
    • Code deployed by non-admins via browser
    • Runs in an isolated environment
