This document outlines the objectives and content for a training workshop on the new features of ADO.NET Entity Framework 4. The workshop will cover enhancements to the EDM tooling including improved support for Model-First development and Complex Types. It will also demonstrate how the Entity Framework runtime is now more fully-featured through the addition of POCO classes, Lazy Loading, Foreign Keys, Model-Defined Functions, and improved N-Tier capabilities. Alternative development styles such as Code-First and Database-First are also enabled.

3. Objectives
• How has the EDM toolset been enhanced?
• What alternative development styles are enabled?
• How is the EF easier to use?
• How is it more fully-featured?
• Does EF 4 address any issues you had with it?

4. Pluralization (v1)

5. Pluralization (v4)

6. Model-First
Database Generated
First (v1) Existing Entity Data
Database Model
Model Entity Data Generated
First (v4) Model Database

7. Complex Types
VS.
1) 1:1 DB Mapping 1) Flexibility from DB shape
2) Could get “crowded” 2) Nicely “organized”

8. Tooling Enhancements

9. POCO
Class Definition
Everything
Navigation Property Definition
Scalar Property Definition

10. Lazy Loading
1) Get Product Get Product
Explicit
2) Access
Category Get Category Database
3) Get Category
Get Product
1) Get Product
Implicit
2) Access Get Category Database
Category

11. Foreign Keys
In theory this
looks reallyperfect!
This is good
In theory this also
looks really good

12. POCO
Lazy Loading
Foreign Keys

13. Model-Defined Functions
Entity SQL
Block
Umm, I’d rather be using LINQ…

14. N-Tier
1) Get Product
Web Service Database
2) Update Product
2) Make
Changes
Combines power of:
1) DataSet
2) DTOs

15. Model-Defined Functions
N-Tier
