I came across a wonderful learning guide for the Entity Framework that explains many essential and complex things about the Entity Framework, including:
- Modeling Entities
- Lazy Loading
- Inheritance
- Working with objects
- Performance
- Working with Stored Procedures
Moreover this 500 pages long learning guide is absolutely free and can be downloaded here with all examples.
