  1. Web 2.0: Building Data Driven RESTful Applications with Microsoft Tools Stephen Forte stevef@orcsweb.comhttp://stephenforte.net

  2. http://speaker/(‘forte’)/bio • Chief Strategy Officer of Telerik • Certified Scrum Master • Active in the Community: • International Conference Speaker for 12+ Years • RD, MVP and INETA Speaker • Co-moderator & founder of NYC .NET Developers Group http://www.nycdotnetdev.com • Wrote a few books: SQL Server 2008 Developers Guide (MS Press) • MBA from the City University of New York • Past: • CTO and co-Founder of Corzen, Inc. (TXV: WAN) • CTO of Zagat Survey

  3. Agenda • What is REST? • What is ADO .NET Data Services (Astoria)? • Consuming ADO .NET Data Services Data • Futures: WCF REST Starter Kit, Astoria Offline

  4. Agenda • What is REST? • What is ADO .NET Data Services (Astoria)? • Consuming ADO .NET Data Services Data • Futures: WCF REST Starter Kit, Astoria Offline

  5. What is REST? • Representational State Transfer • An architectural style developed by Roy Fielding • Resource based not RPC based • Based on HTTP • Standard resource formats • Stateless communication between client and server • GET, POST, PUT, DELETE • Addressable resources + hyperlinking http://example.com/users/ http://example.com/users/{user} http://example.com/locations/ http://example.com/locations/{location}

  6. Web Services v REST Web Services REST HTTP only Resource Focused URI Based XML, RSS, ATOM, XHTML, JSON, and others • Protocol Independent • RPC Focused • Method (Action) Based • XML Based (SOAP)

  7. Agenda • What is REST? • What is ADO .NET Data Services (Astoria)? • Consuming ADO .NET Data Services Data • Futures: WCF REST Starter Kit, Astoria Offline

  8. ADO .NET Data Services • Framework from Microsoft that that facilitates the creation of RESTful data services via HTTP endpoints • Shipped with .NET 3.5 SP1 • Built on top of WCF • Data representation in ATOM or JSON • Automates the exposure of data as RESTful resources • Anything that implements IQueryable<T> and IUpdatable<T> • Entity Framework • 3rd party ORMs • LINQ to SQL, custom data driven CLR classes • Custom URI based querying

  9. Demo-ADO .NET Data Services Walk Through

  10. Service Operations • Additional way to expose resources via URIs • [WebGet] is used for an addressable query • [WebInvoke] is used for insert, update, and delete • Can return a scalar value • IEnumerable or IQueryable • Astoria’s URI exposes the Service Operation • If you use IQueryable you can append query strings to the URI

  11. Data Interceptors • Query Interceptors • Logic that will run when a resource is requested • Can be used to limit the data viewed, log, or perform security check • Change Interceptors • Logic that will run when a change (Add/Edit/Delete) request is made

  12. Demo-Service Operations, Query Interceptors

  13. Securing ADO .NET Data Services • Using the Host’s authentication model • Role based authorization • EntitySetRights • Hiding Sensitive Data • [IgnoreProperties] • QueryInterceptors • ServiceOperations to validate users • Brute force: HTTPS, SSL, IP Filtering • SQL Server Security should not be ignored either!

  14. Agenda • What is REST? • WCF REST Starter Kit • What is ADO .NET Data Services (Astoria)? • Consuming ADO .NET Data Services Data • Futures: Astoria Offline

  15. Programming ADO.NET Data Services • Client side querying via LINQ to ADO .NET Data Services • Proxy • Non Proxy • HTTP Requests for non-Microsoft .NET Clients • GET • POST • PUT • DELETE

  16. Programming from ASP .NET • Server Side • Generate a Proxy and use LINQ to ADO.NET Data Services • Supports full databinding • Updateable • Client Side (Microsoft AJAX) • Need ASP 4.0 JavaScript Preview 3 or better (still beta) • Client side API facilitates client side calls to Astoria from JavaScript • Client side HTML template binding

  17. Demo-Server Side ASP .NET DatabindingChange Interceptors

  18. Programming from Silverlight 2.0 • Full LINQ to Astoria support via a proxy • Must consume all services asynchronously

  19. Demo-Silverlight 2.0 databinding via LINQ to Astoria

  20. Cross Domain Concerns • Need your domain in crossdomain.xml or clientaccesspolicy.xml • If not, build a web service in the same project to consume the Astoria service • Re-expose to Silverlight via WCF • Consume via Linq to XML • Updates need to handled separately

  21. Agenda • What is REST? • What is ADO .NET Data Services (Astoria)? • Consuming ADO .NET Data Services Data • Futures: WCF REST Starter Kit, Astoria Offline

  22. WCF REST Starter Kit • CodePlex download that gives Visual Studio SP1: • New WCF RESTful Templates • Kit expands the http capabilities in WCF • Can build RESTful services • Can consume RESTful services • Including from Ruby, etc

  23. Astoria Offline • Ability to take an Astoria service offline
