  1. Building Data Driven Applications Using WinRT and XAML Sergey Barskiy, Magenic Microsoft MVP – Data Platform Principal Consultant Level: Intermediate

  2. Overview • Dealing with Data in XAML Based Windows 8 Metro Style Applications • WinRT – Windows Runtime

  3. Data Options in WinRT • Persisting Data • Local • Remote / Cloud

  4. Data Binding • INotifyPropertyChanged • INotifyCollectionChanged • Changed since preview

  5. Data Options In Detail • WCF Custom Services • SOAP • REST • Web Api • Part of MVC 4 • OData • WCF Data Services (coming soon..) • Local • Windows.Storage • SQLite (not yet)

  6. Setting up For WCF Development • There is a setting in Project Properties to allow Loopback address or .. • Find Your Application’s ID (HKCU\Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\AppContainer\Mappings • Run CheckNetIsolation CheckNetIsolation LoopbackExempt -a -p=S-XXXXXX • Update Manifest to enable Networking and Internet Client

  7. WCF • WCF Custom Services • Create new WCF Service / Add Reference • Data Contacts / Data Members / Operation Contracts • End point configuration • Querying and updating data • SOAP vs. REST • Soap is easier to use / proxy generation • REST offers better performance and scalability

  8. WCF SOAP Service • Create new Service. • Use Service Contract • Operation Contract • Data Member • Define operations • Build the service • Add Service Reference to generate a proxy in Windows Metro Style project • Handle data binding! • Deploy the service • Setup URL on proxy

  9. WCF REST Service • Create new Service. • Use new template to get a head start • Define operations • WebGet, WebInvoke • Message Type XML vs. JSON • Build the service • Deploy the service • Use HttpClient • Use XML Serializer or JSON Serializer to convert data between service and client • Use headers to set content type

  10. ASP.NET Web Api • ApiController • Define actions • Update route table if necessary / match Urls in client to actions • Match actions to calls • User serializers to convert the data • Handle data binding • Validation

  11. WCF Data Services • WCF Data Services • Subject to changes • There will be a client for WinRT • Data Service Collection? • Define a service • Create proxy (http://odata.codeplex.com) DataSvcUtil.exe /uri:http://localhost/odataservice.svc/ /out:MyModel.cs /Version:2.0 /DataServiceCollection • Configure end point • CRUD operations

  12. Local Storage • Using Isolated Storage • Using Serializers • Helper class

  13. Data Options in WinRT • Summary • Remote vs. local data • Hosting remote data • Azure / Cloud • Hosting providers • Local Storage Options • Files • SQLite (coming later) • Data binding / storage solutions
