posted by gilfgilf 585 days, 22 hours, 17 minutes ago
Monday, October 17, 2011 9:20:31 AM GMT

The problem was a circular reference caused by the DataContractJsonSerializer because of relations between the entity and other entities. In this post I’ll show you how you can use a simple workaround in order to avoid the problem. (more)

Entity Framework Code First Development With WebMatrix   The existing data access story for WebMatrix is the Database Helper. Microsoft's recommended data access technology going forward is the Entity Framework (EF). This article explores how to use the Code First capability offered by EF within an ASP.NET Web Pages application.   The database helper was introduced to provide an easy way for beginners to use SQL in their web pages. As such, it works well, but has its critics. Some of th... (more)

Yesterday I helped a colleague with his ASP.NET MVC 3 site deployment. That colleague implemented the data access layer using EF4.1 Code First. One of the restrictions that he had was that he didn’t have database permissions to create a new database and couldn’t use SQL Express or SQL CE in his application. Instead he had an empty database for his disposal in the hosting environment without a way to ru... (more)

Monday, April 18, 2011 2:01:52 PM GMT Sunday, April 17, 2011 1:12:51 PM GMT
Today I helped a client to solve a problem regarding EF4.1 Code First. The issue that they banged their heads with was an inheritance tree mapping in their model which is spread across two different assemblies. When they run the application they always got the same exception – “mapping and metadata information could not be found for entitytype ‘entity name’”. (more)

We are excited to announce the final Release to Web (RTW) of Microsoft ADO.NET Entity Framework 4.1 (EF 4.1). This is a fully supported, go-live release. What’s in EF 4.1? ADO.NET Entity Framework 4.1 introduces two new features: The DbContext API is a simplified abstraction over ObjectContext and a number of other types that were included in previous releases of the ADO.NET Entity Framework. The DbContext API surface is optimized for common tasks and coding patterns. DbContext can be used with Databa... (more)

There is some confusion out there about a simple question: How can I use Entity Framework? Some developers have heard about reverse engineering models so I decided to write a quick preview to the main features of EF4. This isn’t an in-depth article, but, rather a visual summary of the main four scenarios EF can accommodate.  If you are looking to utilize any of the scenarios described here you might need to seek further documentation and realize that development with Entity Framework is a vast subject an...

In this post you’ll see how Code First and the DbContext class in Entity Framework 4.1 RC will work with WCF Data Services going forward. WCF Data Services in .NET 4.0 was released prior to the Entity Framework 4.1 RC and so does not natively know about the DbContext class. There are numerous posts already on how to get DbContext to work with WCF Data Services in .NET 4.0, including this one by Rowan Miller. These posts talk about how to write some extra code to initialize the DataService class. This is ... (more)

In the past I explained how to use the Code First Fluent API in order to configure and shape your EDM during runtime. One of the problems that might raise when you use the Fluent API as I showed in the previous post is that the OnModelCreating method might become bloated and hard to read. This is the time to get familiar with another model configuration option which is built inside Code First. (more)

EF Feature CTP5: Inheritance Scenarios with Code First Fluent API - Gil Fink on .Net

Tuesday, December 14, 2010 1:58:42 AM GMT Sunday, December 12, 2010 10:35:47 AM GMT
One of the interesting features of Code Firstfluent API is the ability to configure inheritance in your model. Since one of the strengths of an O/RM solution is its ability to map inheritance then this feature is a must in every mapping scenario (may it be Model first, Database First or Code First). In this post I’ll show how to configure inheritance by using the fluent API. (more)

Earlier this week the data team released the CTP5 build of the new Entity Framework Code-First library.  In my blog post a few days ago I talked about a few of the improvements introduced with the new CTP5 build.  Automatic support for enforcing DataAnnotation validation attributes on models was one of the improvements I discussed.  It provides a pretty easy way to enable property-level validation logic within your model layer. You can apply validation attributes like [Required], [Range], and [Regular... (more)
