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

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

Data Binding • INotifyPropertyChanged • INotifyCollectionChanged • Changed since preview

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)

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

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

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

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

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

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

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
