Data Access
RIA Services is Data Layer Agnostic
• Entity Framework• LINQ to SQL• POCO Objects– Custom data access
Getting Started
• Technologies– Visual Studio.NET 2010– C#– Silverlight 4.0– Entity Framework 4.0– WCF RIA Services 4.0
• Initial Resources– www.Silverlight.net – Web Platform Installer
Data Access
RIA Services is Data Layer Agnostic
• Entity Framework• LINQ to SQL• POCO Objects– Custom data access
Alternatives
• Manual WCF• Services– SOAP– JSON– Other
SETTING UP A NEW RIA SOLUTIONDemo
USING RIA SERVICES
Common Scenarios• Querying Data
– LoadOperation• Adding Service Methods• Updating Data
– Changesets– SubmitOperation
• Error Handling• Data Validation
– Data Annotations– HasValidationErrors
• Sharing Code• Lazy Loading
RIA Entities
• Tracked By Context• Notable Attributes:– INotifyPropertyChanged– EntityState– GetOriginal()– HasValidationErrors– RejectChanges– GetConflict– ValidationErrors
Troubleshooting
• Accessing Services via URL• Regenerating DomainContext• Verifying entities are included in service API• “Not Found” Exceptions• Server Side Error Tracking (OnError)
BREAK
ADVANCED TOPICS
UI Considerations
• MVVM• Data Binding• Self Tracking Entities• Context Sharing• Asynchronous Loading
Advanced Topics
• Dynamic Queries• Rejecting Local Changes• Unit Testing• Transaction Support• Concurrency• Caching• Transactions
Data Access Patterns
• IRepository• SQL 2008 Database Project
Security
• Windows Authentication• ASP.NET Forms Authentication• FormsAuthenticationService– UserBase– Injecting UserBase derived classes– [RequiresAuthentication]
Gotchas
• Multiple Domain Services• Method Names• Domain Service Public Interfaces• Generating Temporary Domain Services• Returning Complex Types• EF Limitations:– No Many to Many– Advanced Inheritance
• HasChanges on New Entities
