A common complaint of the Entity Framework is slow insert times for larger datasets. Last night I was trying to insert a catalog of 15k products and it was taking a very long time (I gave up after 5 minutes). I recalled this post a while back from Mikael Eliasson demonstrating SqlBulkCopy using .NET. I […]
Read MoreIf you?ve taken the jump to try out the new Entity Framework Code First and you?re allowing it to generate your database for you, you?ve most certainly run into the lack of migrations/updating existing schema support. Currently EF Code First will only create a database and won?t update a database with changes necessary to bring […]
Read MoreI was asked the other day if I knew of a way to do GetById generically with Entity Framework. I thought that I had done something similiar in the past and the task would be easy, but it turned out to be a little bit more complicated. After searching some forums and blogs, I came […]

That is because they are actually stored as a resource in the assembly you created your entity model. When you create […]
Read MoreIn my previous two posts I talk about simple EF4 mappings and some common abstractions I like to work with for my entity persistence operations. In this post I want to take all of the setup code necessary for EF configuration and registration and encapsulate it along with the standard boiler plate IOC container code […]
Read MoreIn my previous post I demonstrated how to create a simple mapping using the latest EF4 CTP. In this post I will look at how I can customize some infrastructure code in an attempt to align EF POCO ?Code Only? with existing patterns, while potentially increasing reuse and testability. A popular pattern for ORM data […]
Read MoreThe latest EF4 CTP released on November 12th includes updated support for POCO’s (Plain Ol’ CLR Objects). Although we could use POCO’s in the previous CTP, we still had to create an EDMX artifact to model our entities, thus leading to a bit of duplication. In this post I want to take a look a […]
Read MoreI had the opportunity to present at the MSDN Unleashed event here in Boise. Thanks to everyone who made it down, it was a great day packed with new technology. (unfortunately my stay was cut short) I was asked if I could make my slide deck and code samples available, so here they are. Enjoy. […]
