• Creating Collections of Entity Objects
  
  Magazine/Issue: CoDe Magazine, 2013 May/Jun
  Release Date: Saturday, April 06, 2013
  Quick ID: 1305031
  Almost every programmer knows (unless you have been living under a rock for the last five years or so) that you should be using classes for all of your programming. You should also be using collections of objects instead of using a Data Reader, a DataSet, or a DataTable in your applications. The reasons for using collections are many and are explored in this article.
  
  
• Entity Framework 4.1: Code First
  
  Magazine/Issue: CoDe Magazine, 2011 Jul/Aug
  Release Date: Sunday, July 03, 2011
  Quick ID: 1108051
  The Entity Framework team at Microsoft has been making several improvements since the launch of v4 with Visual Studio. The biggest of these is the capability to use a Code First or Code Only development model. Previously, if you wanted to work with the Entity Framework, you had to use either a Database First or Model First development model.

  A common requirement in building applications is the need to serialize objects and pass them across tiers between the server and the client. These objects typically hold references to each other, and managing this “graph” and tracking all the changes so that they can be properly persisted to the database can get complicated quickly.
  
  
• POCO Support Comes to Entity Framework 4

  When Microsoft first released the Entity Framework, agile developers roundly criticized it. These developers hold the tenets of domain-driven development and testability very high. The classes generated from the Entity Data Model (EDM) are very tightly bound to the Entity Framework APIs by either inheriting from the EntityObject or implement interfaces that allow the classes to participate in change tracking and relationship management.
  
  
• ASP.NET MVC & the ADO.NET Entity Framework
  
  Magazine/Issue: CoDe Magazine, 2010 Sep/Oct
  Release Date: Friday, August 20, 2010
  Quick ID: 1009071
  Both ASP.NET MVC and the ADO.NET Entity Framework are both very popular topics right now in the developer community.Having spoken at various user group meeting and code camps it is very obvious to me what topics a lot of developers are interested in. I see that sessions about ASP.NET MVC or the Entity Framework are always packed with developers eager for more information. The focus of this article is the Entity Framework, but in the context of an ASP.NET MVC application. As such, I am assuming at least basic understanding of ASP.NET MVC but little-to-none with Entity Framework.
  
  
• Developing Database Agnostic Applications with Entity Framework
  
  Magazine/Issue: CoDe Magazine, 2010 Mar/Apr
  Release Date: Friday, February 12, 2010
  Quick ID: 1003101
  Microsoft released Entity Framework, an ORM (Object Relational Mapping) tool, in 2008.Entity Framework gives developers the ability to be abstracted from the underlying relational database management system and allows them to talk to a database using familiar LINQ-based syntax.
  
  
• What’s New in Entity Framework 4, Part 2: Modeling Changes
  
  Magazine/Issue: CoDe Magazine, 2009 Nov/Dec
  Release Date: Friday, October 23, 2009
  Quick ID: 0911121
  If you have been working with the ADO.NET Entity Framework, you have probably been extremely eager to get your hands on the next version that is now part of Visual Studio 2010 and .NET 4.0. Long referred to as “EF Version 2,” this version is now called Entity Framework 4 or EF4, to align with the .NET Framework 4.0 version.

• 8 Entity Framework Gotchas
  
  Magazine/Issue: CoDe Magazine, 2009 Jul/Aug

  Quick ID: 0907071
  As a developer, it is no surprise to encounter unexpected behavior when working with a new technology.Microsoft added the Entity Framework (EF) to ADO.NET with the .NET 3.5 Service Pack 1 released in 2008 enabling developers to incorporate a data model directly in their application and interact with their data through the model rather than working directly against the database. For background on EF, see my previous article, “Introducing ADO.NET Entity Framework” in the Nov/Dec 2007 issue of CODE Magazine.
  
  
• Data Access Options in Visual Studio 2008
  
  Magazine/Issue: CoDe Magazine, 2008 Sep/Oct
  Release Date: Friday, August 22, 2008
  Quick ID: 0809091
  With Visual Studio 2008 and .NET 3.5, developer’s data access options have increased substantially. In addition to using ADO.NET to create DataReaders or DataSets, Microsoft has added LINQ to SQL and Entity Framework as well as ADO.NET Data Services, which leverages those two. In addition to these new options, there are new syntaxes to learn. LINQ, which is built into Visual Basic and C#, has one implementation for LINQ to SQL and another for LINQ to Entities. In Entity Framework, you have the option to use LINQ to Entities as well as two other ways of querying with Entity SQL, as you can see in Figure 1.

  The challenge of bringing data from efficient storage engines such as SQL Server into object-oriented programming models is hardly a new one. Most developers address this challenge by writing complex data access code to move data between their applications and the database. This requires an understanding of the database so that you can access data either from the raw tables, from views, or from stored procedures.
  
  
• An Entity Data Model for Relational Data Part I: Defining the Entity Data Model
  
  Magazine/Issue: CoDe Focus Magazine, 2007 - Vol. 4 - Issue 3 - Data Programability
  Release Date: Wednesday, October 03, 2007
  Quick ID: 0712022
  Microsoft’s Entity Data Model allows you to define an application-oriented view of your data consistent with how you reason about that data.Part I of this article describes the Entity Data Model and how it enables you to represent real-world concepts in a way that makes relationships between related pieces of data more explicit and easier to query, navigate, and consume than through the traditional relational database model. Part II of the article discusses how Microsoft’s ADO.NET Entity Framework provides a flexible mapping of an application-oriented conceptual schema in terms of the Entity Data Model to existing relational database schemas. Shyam Pather’s article, “Programming Against the ADO.NET Entity Framework” completes the picture by describing the actual programming model and API exposed by the framework.
  
  
• An Entity Data Model for Relational Data Part II: Mapping an Entity Data Model to a Relational Store

  Release Date: Wednesday, October 03, 2007

  The ADO.NET Entity Framework allows you to define an application-oriented view of your data consistent with how you reason about that data, and map that conceptual view to existing relational schemas.Part I of this article described the Entity Data Model and how it enables you to model real-world concepts in a more natural way. Part II of the article describes how that Entity Data Model is used within the ADO.NET Entity Framework to define an application-oriented conceptual view of your data, and how that view can be flexibly mapped to existing relational schemas. Shyam Pather’s article, “Programming Against the ADO.NET Entity Framework” completes the picture by describing the actual programming model and API used by developers to work with data using the ADO.NET Entity Framework.

  The ADO.NET Entity Framework raises the level of abstraction at which developers work with data.Rather than coding against rows and columns, the ADO.NET Entity Framework allows you to define a higher-level Entity Data Model over your relational data, and then program in terms of this model. You get to deal with your data in the shapes that make sense for your application and those shapes are expressed in a richer vocabulary that include concepts like inheritance, complex types, and explicit relationships.The ADO.NET Entity Framework raises the level of abstraction at which developers work with data.Rather than coding against rows and columns, the ADO.NET Entity Framework allows you to define a higher-level Entity Data Model over your relational data, and then program in terms of this model.
