Honest Illusion : Creating an Entity Framework connection from another

Tue, 03 May 2011 22:02:24 GMT

Database connection strings used to be simple. Well, simple, once you learned the arcane syntax, But, at least they had stayed the same for about a decade. But with the EntityFramework, they took on an even more arcane "connection string - within -a -connection string" format. And while the inner connection string related to your database, the wrapping connection string was intimately tied to the entity context.

Mon, 11 Oct 2010 22:20:15 GMT

I highly recommend this book. No further knowledge about Entity Framework is required. So you don't have to know anything about EF1 in order to read and gain benefit of this book. Great effort spent on this book by the authors and the publisher. You'll get a great value with reasonable amount of money compared to the information provided in this book.

Mapping Conceptual Model Function to Complex Type in Entity Framework

Thu, 08 Apr 2010 07:22:40 GMT

You might hear of KiGG, the open source project that is currently live as http://dotnetshoutout.com. I wanted to expose part of KiGG data as an OData Service for read only. But I figured out that exposing raw KiGG schema might not be useful. So I had to choose between 2 options that were up to my mind: * Build some views on the physical store -database-. Create a new entity data model for those views and use the new data model context for DataServiceContext. * Use Entity Framework 4.0 conceptual model function feature with complex types to simulate views. It's like building views on the conceptual model itself and not the store model.

Introducing Entity Framework Unit Testing with TypeMock Isolator

Sun, 06 Sep 2009 19:07:12 GMT

One of the challenging things with current version of Entity Framework, its leakage of testability. Which means when you build an application or module (e.g. Repositories) that depends on entity framework, it will be very hard to unit test your code isolated from Entity Framework. This might lead to conduct Integration Testing which will require a connection and interaction with underlying data store (database). You might think of using Mocking to mock or fake Entity Framework data store dependent calls. But sadly Moq and Rhino Mock mocking frameworks do not support this. And you'll end up hitting the wall. Both frameworks are great useful and I personally use Moq for a while now and very happy with it. But no one can deny limitations when exist.

Multiple database support with Entity Framework

Tue, 18 Aug 2009 18:53:27 GMT

One of the features introduced in Entity Framework is being database independent. Which mean each database provider can support Entity Framework by implementing its provider. This feature allows you build applications independent from the underplaying database provider. In this post I'm going to show how to build an application that support multiple databases using same conceptual model made by Entity Framework.

Introducing DataLoadOptions for Entity Framework ObjectContext

Sat, 16 May 2009 23:11:43 GMT

On my previous post "What about DataLoadOptions for Entity Framework ObjectContext?" I was suggesting another way to define eager loading for Entity Framework. In this post I will introduce my DataLoadOptions for Entity Framework ObjectContext. The beginning: Actually Eager and Lazy loading on Entity Framework is not that much fun like in Linq to Sql. However this is going to be improved in EF4. Here I will focus on eager loading and my slight improvement to define eager loading in Entity Framework.
