This is an introduction session about Microsoft Entity Framework 4.0 (year 2011), since then the technology has evolved and matured in many ways and some of the limitations had been mitigated.

1. Introducing Entity Framework EF v1.0

2. History of ADO.Net Object Relational Mapping {ORM} What is Entity Framework? Entity Framework Architecture Entity Data Model {EDM} Entity Client & Object Services LINQ to Entities & Entity SQL {eSQL} Agenda

3. Load Related Objects Inheritance in Entity Framework Entity Framework providers and multiple database support Entity Framework Limitations External Tools References Agenda (Cont.)

4. History of ADO .Net

8. Object Relational Mapping {ORM}

9. ORM Basics & Concepts

10. What is Entity Framework? Why it is considered an ORM?

11. What is Entity Framework? An ORM framework, Why? Database Independent Extensible Part of Microsoft .Net framework 3.5 SP1

12. Getting Started

13. Entity Framework Architecture

14. Entity Framework Architecture

15. Entity Data Model (EDM) What is Entity Data Mode?

16. Entity Data Model (EDM)

17. EDM in Action

18. Entity Client & Object Services

19. Entity Client EntityClient Provider for Entity Framework System.Data.EntityClient Abstracts DBMS Providers for Entity Framework Architecture

20. Entity Client in Action

21. Object Services

22. Object Services in Action

23. Break (30 minutes)

24. LINQ to Entities & Entity SQL

25. LINQ to Entities What is LINQ LINQ to Objects LINQ to XML LINQ to DataSets LINQ to SQL And more E.g. (LINQ to Twitter, LINQ to Flickr etc…) LINQ to Entities

26. LINQ to Entities in Action

27. Entity SQL (eSQL) Supported NOT Supported SQL based Provider neutral Supports EDM types First class collections Canonical functions DML statements (insert, update, delete) DDL statement (create, alter, drop) Grouping functions (CUBE, ROLLUP, GROUPING_SET Does not support the * construct

28. Entity SQL in Action

29. Entity SQL Vs LINQ to Entities Dynamic queries (LINQ is compiled) Store Function/Procedures is only supported in eSQL

30. Load Related Objects

31. Entity relation mapping (one to one, one to many, many to many) Deferred Loading Vs Eager Loading Vs Explicit Loading ObjectQuery<T> Class EntityCollection<T> Class EntityReference Class Load Related Objects

32. Load Related Objects in Action

33. Inheritance in Entity Framework

34. Inheritance in Entity Framework Table-per-Hierarchy (TPH) Table-per-Type (TPT)

35. One table in storage to maintain data for all the types in an inheritance hierarchy. Table-per-Hierarchy (TPH)

37. Inheritance in Action

38. Entity Framework Providers Multiple database support

39. Entity Framework Providers MySQL Connectoret (MySQL) Devart (Oracle, MySQL, SQLite and PostgreSQL) IBM (DB2, Informix and U2 databases) Phoenix Software Solutions (SQLite) Npgsql (PostgreSQL) Sybase SQL Anywhere (SQL Anywhere 11) Firebird (Firebird) VistaDB (VistaDB 4.x) Multiple Database Support in Entity Framework

40. Multiple Database Support

41. Entity Framework Limitations

42. Known Issues and Considerations in LINQ to Entities Ordering Information Lost Nested Queries. Nested Queries May Fail with SQL Server 2000 Unsigned Integers Not Supported Enums not supported Referencing Non-Scalar Closures Not Supported Custom extension methods Not Supported Some common sense methods not supported (Single, SingleOrDefault) Entity Framework Limitations

43. Entity Framework VS.Net Designer Limitations limitations in Entity SQL DDL not supported DML not supported (insert, update, delete) Design issues No Persistence Ignorance support a.k.a POCO Leakage of Testability I am sure there might be more  Entity Framework Limitations (Cont.)
