@PDC09 – Day 3 – Developing custom applications in SharePoint 2010 using ASP.net, WCF, REST

SharePoint Web Services

• REST
• Client Object Model
• ASP.net
• WCF

REST

• Access to sharepoint lists and library data ( …/_vti_bin/listdata.svc)
• Lists and List items map to resources (listdata.svc/Employees(123) )
• Operation are mapped with HTTP verbs (GET, POST . . )
• Based on ADO.net Data Services
  • Flexible URL conventions for querying data
    • listdata.svc/Employees?$filder=JobTitle eq ‘SDE’
    • $orderby=Fullname
  • Multiple representations
    • JSON and Atom (full AtomPub support)
  • Batching, ETags, Paging, Documents

Demo . . .
REST query is converted to CAML query…..

Integrated Development Experience in VS 2010 and VS 2008 SP1 using just “Add Reference”

• Data Source configuration has a new item to connect to SharePoint
• Master Details type application development

Client Object Model

• Supports
  • Site Operations
  • Lists, ListItems
  • content types, fields
  • but not administration namespace, farm objects
• Implemented as WCF Service
  • …/vti_bin/client.svc
  • It passes batch command to the WCF service (in XML)
  • than the server executes and returns the data back to client (in JSON Other SharePoint Web Services
• Advanced Operations
  • User Profiles
  • People
  • Search
  • Enterprise Metadata
  • Document Coauthoring
  • Excek REST web services
  • Publishing
  • Workflow
  • BCS web services
  • ….. see MSDN
• we can also extend sharepoint and create custom web services
  • ASP.net
  • WCF (is now recommended for sharepoint 2010 custom service development)

WCF Services

• Problem
  • IT Admin configures IIS
    • Different authentication schemes can be configured (Basic, Claims, Windows Integrated . . .)
    • Multiple IIS address bindings
  • Developer configures WCF Service endpoint
• Solution
  • Dynamic (Programmatic) configuration
    this would be in RTM only
  • SOAP
    • Specify Service Factory in SVC file
    • Add MEX endpoint behavior attribute to the service class
    • Deploy SVC service to ISAPI Folder
  • REST

Demo of creating custom WCF service inside sharepoint

• sandbox solutions doesn’t support services

WCF Service Configuration

• Service.svc
• SharePoint Service Factory creates the endpoint based on all authentications
  • service.svc/negotiate
  • service.svc/ntlm
• SharePoint Http Modules
