ASP.NET Data Access Content Map
This topic provides links to documentation resources about how to access data in ASP.NET web applications, primarily by using the Entity Framework and SQL Server.
If you know a great blog post, stackoverflow thread, or any other link that would be useful, send us an email with the link.
We are seeking feedback on some experimental new approaches to presenting annotated lists of recommended resources. Some of them have a narrower scope than this content map; for a deployment example, see How to deploy an ASP.NET web application to a Windows Azure Web Site using Visual Studio. Another example is How to secure an ASP.NET MVC app .

Using Entity Framework Code First
- Getting Started with EF 4.1 using MVC 3 (Covers a wide range of Entity Framework Code First scenarios but does not include Migrations.)

- Data Developer Center - Entity Framework (MSDN. For a guide to Entity Framework documentation that has been created and maintained by the Entity Framework team, see the Get Started link.)
See also Books about the Entity Framework and Additional Entity Framework Resources later in this topic.
Using Entity Framework Code First Migrations

Using Entity Framework Database First or Model First (the EF Designer)
For current resources on using the Entity Framework designer, see the MSDN Data Developer Center. See also the Books about the Entity Framework and Other Entity Framework resources sections later in this topic.
The following resources are older. They are useful if you want to use version 4.0 of the Entity Framework, and you want to use a data source control for data binding in a Web Forms application.
- Getting Started with the Entity Framework 4.0 (Shows how to use the EntityDataSource control.)
- Continuing with the Entity Framework (Shows how to use the ObjectDataSource Control. Includes a tutorial on concurrency handling, a tutorial on EF performance, and a tutorial on what's new in EF 4.0.)
Loading Related data in Entity Framework (Lazy Loading, Eager Loading, and Explicit Loading)
- Reading Related Data with the Entity Framework in an ASP.NET MVC Application (Code First, MVC sample application. The methods shown apply also to Web Forms model binding.)
- Data Developer Center - Loading Related Entities (MSDN. The Entity Framework team’s documentation about loading related data.)
Optimizing Entity Framework performance
- Advanced Entity Framework Scenarios for an ASP.NET Application (Shows how to execute your own SQL statements or call your own stored procedures, how to disable change detection, and how to disable validation when saving changes.)
- Performance Considerations for Entity Framework 5 (MSDN)
- Performance Considerations (Entity Framework) (MSDN)
- Maximizing Performance with the Entity Framework in an ASP.NET Web Application (Applies to Entity Framework 4.0.)
- See also Optimizing ASP.NET data access later in this topic.
Handling Concurrency in an Entity Framework Application
- Handling Concurrency with the Entity Framework in an ASP.NET MVC Application (Code First, DbContext API, using an MVC sample application.)
- Data Developer Center – Optimistic Concurrency Patterns (MSDN. The Entity Framework team’s concurrency documentation.)
- Handling Concurrency with the Entity Framework in an ASP.NET Web Application (Applies to Entity Framework 4.0. Database First, ObjectContext API, using a Web Forms sample application.)
Books about the Entity Framework
- Programming Entity Framework: DbContext by Julie Lerman and Rowan Miller
- Programming Entity Framework: Code First by Julie Lerman and Rowan Miller
Both of these books are up-to-date with the most current recommended techniques, and they provide a much more comprehensive yet easy-to-follow introduction to the Entity Framework than anything available on the Internet. Another book, Programming Entity Framework by Julie Lerman, is larger and more comprehensive but it is older and many of the techniques it covers are no longer the recommended way to use the Entity Framework. See also the list of books recommended by the Entity Framework team at Data Developer Center - Books on the MSDN site.
Other Entity Framework Resources
- Entity Framework (ADO.NET) team blog (One of the best resources for the most current information and announcements of new enhancements.)
- Julie Lerman's blog (Julie Lerman is the author and co-author of several Entity Framework books and courses, and her blog is another good source for current information and announcements.)
- MSDN Magazine (See the Data Points column, which is frequently about topics related to the Entity Framework.)
