EF POCOs and GetObjectStateEntry
November 24 2009
Even when working with POCOs, the EF’s ObjectContext can track the objects using ObjectStateEntry objects just as it does for entities that inherit from EntityObject. I was thinking about ObjectContext.ObjectStateManager.GetObjectStateEntry. This method has two overloads. One takes an entity and the other takes an EntityKey of an entity. Then it returns… read moreSlides and Demos from Recent Entity Framework 4 Presentations

I have gathered up my slides and demos from Oredev and DevConnections and put them on the internet. The PPTs are on Slideshare. The demos are on the downloads page of my book’s website: www.learnentityframework.com. That page also has the links to the slideshare urls. Here’s what you’ll find on the downloads page: 1. DevConnections… read moreAgile EF4 Repository: Part 3 -Fine Tuning the Repository

November 20 2009
Part 1 of this series, Agile Entity Framework 4 Repository- Part 1- Model and POCO Classes, covered the classes, the model and the context. Now we will look at the repository. Since the model & context are also part of the repository, my working title for this part of the repository… read moreAgile Entity Framework 4 Repository: Part 1- Model and POCO Classes
November 19 2009
I’m going to lay out this out in a few blog posts because it’s complex. As I am not a TDD developer, I won’t be starting from the tests. I’m doing this in a fashion which is logical to me. But that will mean you’ll get some teasers along the… read moreAgile Entity Framework 4 talks at NotAtPDC Online today

Not at PDC? Well, yeah PDC is having some sessions streamed, like keynotes etc, but for the rest of us, there’s www.notatpdc.com. Two days of live presentations on lots of great topics. Here’s a screenshot of the schedule so far (note that it is CENTRAL time). Go to the website to… read moreMemorial to a tree – yes, a tree
November 18 2009
Five years ago, I wrote this blog post about a tree on our property. I see this tree all day long while I'm working. This tree is like the ocean. In the summer when it is full green and the wind is blowing, it is absolutely mesmerizing to watch it.… read moreVs2010 IntelliTrace and Entity Framework Database Interaction
November 17 2009
I knew that Intellitrace existed, but not until I saw Nikhil Kotahari’s tweet from PDC09 “Cool VS demo - intellitrace - see your db queries, and track it back to your LINQ code #pdc09” did I think to look at what IntelliTrace reports with respect to Entity Framework database interaction. I fired up… read moreSelf-Contained Entity Framework Models and ASP.NET Dynamic Data
November 15 2009
In an earlier post, I wrote about the new awesomeness that ASP.NET 4.0’s Dynamic Data brings to many to many relationships. I frequently notice that most DD demos demonstrate creating the data model within the same project as the DD website. Even though a typical Dynamic Data app is for RAD development… read moreAn Improved Entity Framework Tip for EF4 thanks to Zeeshan
November 13 2009
In my EF Tips & Tricks talk that I just did at DevConnections, I have a suggestion to reduce redundant methods where you might expose queries to generate reference lists. E.g. static List<CustomerType> CustomerTypeList(MyEntities context) { return context.CustomerTypes.OrderBy(ct => ct.Type).ToList(); } static List<States> StatesList(MyEntities context) { return… read moreMy Twitter Notes from Scott Guthrie Keynote at DevConnections

I'm at DevConnections and sat in on Scott Guthrie's keynote. I tweeted a lot of notes throughout the session. http://www.twitter.com/julielermanvt I'll try to consolidate them at some point. There's a lot coming from te #devconnections hash on twitter. You don't need to have an account to read this stuff. I didn't use the hashtag… read moreNovember 08 2009
The hard part about going from one conference to the next is the lack of closure. Not that Oredev was bad and I need closure, but I would like to process it a little bit. This was my third conference in Sweden in the past 2 years, but the first… read moreMSDN Guidance on ASP.NET MVC vs WebForms and its Impact on my EF + ASP.NET Work
November 07 2009
Last year at the fall 2008 DevConnections conference, I was very happy to hear Scott Guthrie providing a clear message about web forms vs. MVC in ASP.NET 4.0. Now, I am seeing something that is new for MSDN Documentation, not only similar clarity but actual guidance on when Microsoft suggests to… read moreASP.NET 4.0 Dynamic Data and Many to Many Entity Framework Entities
