SETTING UP A NEW RIA SOLUTION Demo

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)
