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
Demo
SETTING UP A NEW RIA SOLUTION
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
