This coming Wednesday 9 September I’ll be doing a presentation at the free, online CodeRage 4 conference:
How to Think Like the ADO.NET Entity Framework
(and why you might want to bother learning to do so in the first place)
In order to use the ADO.NET Entity Framework effectively, you must understand its value-based data model, which is [...]
Calling IQueryable<T>.Skip(0) seems like it should be "free." In other words, since it will have no effect on the resulting data, there should be little to no performance cost for calling it. But this is demonstrably not true in LINQ to Entities, and it occurs to me that LINQ providers are not required to optimize [...]
Also tagged linq, PagedListIf you spend enough time with the PagedList class that I’ve been using for paging in the method which supplies data to jqGrid, it’s a near-certainty that sooner or later you will see a LINQ error with Count in the call stack. The error may seem confusing, because it has nothing to do with Count. [...]
Also tagged asp.net mvc, jqGrid, jQuery, linq, linq to sql, unit testingA couple weeks ago, I wrote a post noting that I liked the lightweight nature of the Ruby web framework Merb. Today comes the news that Merb and Rails will be merging in Rails 3. People who see Merb as the "anti-Rails" seem to find this surprising. But people who see Merb as "Rails done [...]
Also tagged architecture, asp.net mvc, dynamic data, merb, railsIn the past couple of weeks, I’ve had occasion to look fairly closely at the ADO.NET Entity Framework, and compare it to NHibernate. Of course, before I even started, I went out and read what other people had to say on the subject. Many people point to this post by Dan Simmons as approximating the "official" Microsoft position on the subject, and commenters around the web seem to focus specifically on what band calls "a [not yet delivered, but] much larger vision of an entity-aware data platform." That’s interesting, but there are differences which exist today which are perhaps even more interesting.
