I've had some requests lately to write some articles that work with LINQ to SQL. I've ben focusing on the Entity Framework a lot due to its vast nature and that fact that its still relatively unknown to many people. So I am going to work on a LINQ to SQL project that ties into a multi tier model...

Yeah, I know its expected that when a product is in beta and its ancillary features are released in a CTP that there will be some "interesting" issues in getting set up. But its getting a bit out of control (in a good way) lately with all of the installations related to the Entity Framework...

In the March issue of MSDN Magazine's Data Points column I explore a variety of the Standard Query Operators and how they work with LINQ. Read more about standard query operators at johnpapa.net ...  

We all make mistakes ... I know I certainly do. Today I made one that only set me back about 10 minutes ... but I admit I felt silly after I realized what I did wrong. Today I created a new VS 2008 project, added an Entity Data model (aka EDMX file) to the project, and began setting up my EDM. When i...

My July 2007 Data Points column has been posted to the MSDN Magazine web site . This edition is titled "ADO.NET Entity Framework Overview" . I wrote this using the March CTP and then revised it using the Orcas Beta 1, so the code included works in the most recently available bits. Knowing that...

Due to the lack of a designer and because I am very curious, I’ve been digging through the XML for the CSDL, MSL and a little bit into the SSDL schemas for the Entity Framework’s Entity Data Model. Even if you are waiting for the Designer to be released (date TBD) it cannot hurt to get familiar...

I agree that there is quite a bit of work to do yet with the Entity Framework. Earlier today Scott posted his thoughts on the challenges that the Entity Framework faces. He makes some good points which really show how the approach to application development greatly influences which tools and development...

The Data Access Team published a great post that has some superb explanations on how to make the Entity Framework use stored procedures for inserts, udpates and deletes . (It does not yet support stored procedures for retrieving data.) Obviously there are pieces missing, as Shyam states (such as retrieving...
