@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

@PDC09 – Day 2 – Networking and Web Services with Silverlight

                                                                   (Rough notes from the session)

Getting Data into Silverlight :

  • Message Pattern
    • Request / Reply
    • Duplex (email sending, confirmation received from server)
    • Multicast (Server send only 1 copy)
  • Interaction Model
    • Operation centric (service and client in memory passing messages)
    • Resource centric (start with data or data model, CRUD)

Data Access Examples :

  • “Forms over data” E2E business app  
    (Request / Reply Message Pattern solution / Travel Agent Application example)
    • WCF RIA Services (System.Web.DomainServices)
    • Perscriptive model for CRUD services
    • Great tooling to maximize productivity
    • E2E data: sorting, paging, filtering, validation
  • Access data from third party REST service  (System.Net )
    • ClientHttp networking stack (WebRequestCreator.ClientHttp)
      • Integrated with the OS networking stack
      • Support common BrowserHttp stack features for consistent experience
      • Basic, Digest and NTLM authentication is supported in client stack
    • BrowserHttp stack
  • Access your database or SharePoint data model using REST (System.Data.Services)
    • WCF Data Services
      • Formerly ADO.NET data services
      • Services with RESTful interface and a set of conventions designed for easy data sharing
    • What is Data Services?
      • Server framework for .NET, other coming
      • Clients for silverlight
    • Accessing Data Services
      • Silverlight ClientHttp stack still an option
      • Data services client more usable as it knows the details of the data service interface
      • Features
        • Full abstraction on top of the services – no need to serialize
        • Data as objects with automatic change tracking
        • LINQ to querie
      • WCF Programming Model
        • Programming Model
          • Core Services
          • Web HTTP Services
          • Data Services
          • RIA Services
          • Workflow Services
        • Service Model
        • Channel Model
  • App which accesses server business logic (Operation Centric – System.ServiceModel)
    • Generated proxies
    • Serialization of objects on wire
    • High performance
    • Binary Message Encoder (server throughput increase / message size reduction)
      • Its the default encoder
      • It can also be used with IIS Gzip compression
    • WCF Features
      • Faults enabled in SL3
      • To get full exceptions, use ClientHttp stack
      • Security in cross domain scenarios enabled
        • Normally use browser-managed security (generally not safe for cross-domain use)
        • Transport security with message credentials in cross-domain scenarios
          (Browser never sees the credentials and can’t cache it for malicious things)
  • Chat app (System.Net)
      • Duplex Messaging
        • Server push is compelling when server has to notify client of events (email server)
        • Internet: PollingDuplex (HTTP-based)
          • SL4 – performance enhancements and scale across machines (for azure)
        • Intranet: NetTcp (TCP sockets based)
          • Also works for request / reply services
        • Both of above use same programming models, just need to change the binding
  • Streamed data (video, stock prices) inside an intranet  (System.Net)
    • Multicast Messaging
      • Scales to a large receiver population
      • Two key shapes
        • Single source multicast
        • Any source multicast
      • Need to expose a policy responder (just like sockets and http)
        • SL4 – policy file is going away for both sockets and multicast if app is elevated

@PDC09 – Day 2 – Developing Advanced Applications with Windows Azure

                                                                   (Rough notes from the session)
By Steve Marx, Technical Strategist, Microsoft Corporation

LB –> Web Role + Worker Role

Official shipping version of the Table Storage SDK is available now

What we’ll Build – Search application using IIS + SMTP  + Web and Worker Roles
  • Three role architecture
    • Web UI (ASP.net MVC)
    • SMTP Server (TCPListener)
    • Search (Lucene.NET)
  • New Features we’ll take advantage of
    • Inter-role communication
    • Non-HTTP endpoints
    • Role instance lifecycle
    • VM sizes
    • Local storage
HOW TO: Model your application
  • Draw the boxes and arrows
  • Each box is a role
    • Which receive traffic from the internet
    • Which need IIS?
    • Which receive internal communication?
Receiving Traffic. Input Endpoints
  • Different ports on the same domain
  • Always load balanced
  • Declared in ServiceDefinition.csdef
  • Handled by IIS in web roles
  • Handled by your code in worker roles
  • API to find
The instance could should always be atleast 2 or else SLA isn’t valid.
Azure Storage Explorer in codeplex

Input Endpoints Demo :  Set the configurations in the xml file
As an Aside about Email
  • Spammers will use Windows Azure. (sending email should not be done via azure as the IP is not trusted)
Asynchronous work without a Queue
  • Queues deliver messages to one worker
  • We need every worker to see the messages
  • Use a table instead
    • build your own secondary index
    • order references
    • (Beware of clock drift!!)
HOW TI: DO Initialization
  • don’t want traffic until we are listening
  • role instance lifecycle lets us prepare
    • both web roles and worker roles
    • OnStart() - “busy” state, initialization
    • Run() – do work
    • OnStop() – traffic stops, graceful shutdown
HOW TO: Internal Endpoints
  • Declare endpoints in servicedefinition.csdef
  • API to find out what port to listen on:
    RoleEnvironment.CurrentRoleInstance.InstanceEndpoints[“”]
For internal endpoints always rely on the API to provide the port number, do not assign any port number.
HOW TO: Get more RAM
  • RAMDirectory puts everything in memory
  • If we have lots of data, we need lots of RAM
  • Choose among four VM sizes:
    • Small
    • Medium
    • Large
    • Extra Large
  • Simple edit to servicedefinition.csdef
    <WorkerRole  vmsize=”ExraLarge” />
HOW TO: Save the Index
  • Lucene.NET writes files to the local system
  • Preserve those across reboots/upgrades : 
    <LocalStorage cleanOnRoleRecycle=”false” />
  • Consider writing state on OnStop()
    (this is the to write I was on record XX and save the last state)
Using In-Place Upgrade
  • Rolling Upgrade
  • Specify which roles to upgrade
  • Keep local storage intact
  • Great for stateful roles

Call of Action:
  • Any instance can talk to any other
  • Don’t need IIS to listen for traffic
  • Use the role instance lifecycle
  • Choose different VM sizes
  • In-Place upgrades
