The document introduces the Silverlight Cookbook, which provides recipes for building Silverlight applications using practices like MVVM, coroutines, commanding, querying, and domain events. It discusses traditional and recommended Silverlight architectures, and frameworks that can be used like Caliburn Micro, AutoFac, and NHibernate. The presentation provides background on these topics and examples from the Silverlight Cookbook.

3. Defining an architecture
1. Collect non-functionals
2. Determine deployment environment
3. Determine usage
4. Select engineering principles
5. Read between the lines
6. Select technology
7. Define reference architecture
8. Build & adapt

6. The traditional
architecture…

7. Shell Views (XAML + C#)  Well-known
 Rich domain models
Silverlight 5
View Models
 Many frameworks
Application Controller
 Very flexibele
Service Agent × Lots of work
× Lots of plumbing needed
× Not using RIA frameworks
DTOs
× DTO conversion troubles
× No eager loading
WCF
Service Interface
Service Actions Domain Model Workflows
Nhibernate 3.x
(+ Fluent)
Repositories Unit-of-Work Service Agents
Backoffice External
Database System Service

9. Shell Views (XAML + C#)  Easy to build

Silverlight 5
View Models
Simple domain models
 Less plumbing needed
Application Controller
 No DTO conversions needed
Domain Context  Maximizes RIA frameworks

WCF RIA Services
Great for CRUD
 Batching
Changesets
× CRUD-based
× Domain model not possible
Domain Service
× No dynamic relationship
Entities Business Actions loading
× Almost enum support
Entity Framework Service Agents
× No 2nd level caching
Backoffice External
