I finished up my talks at ASP.NET Connections yesterday and wanted to get the code posted as well as links for the additional topics covered in the Silverlight animation session.  Here they are: Building N-Tier ASP.NET Applications with LINQ Code Silverlight 2 Animations Code SilverlightFX Farseer...

LINQ to SQL is fascinating - the more I work with it, the more I hate it, and then love it again all at the same time. Recently we had an issue while using it in a slightly older version of our N-Tier WCF application which uses LINQ to SQL as it's primary ORM solution (yes, I know). I'll try to briefly...

If you are using Linq to SQL, instead of writing regular Linq Queries, you should be using Compiled Queries . if you are building an ASP.NET web application that’s going to get thousands of hits per hour, the execution overhead of Linq queries is going to consume too much CPU and make your site slow...

I want to tell you about List<T>.ForEach method and one of my famous blonde moments when I was debugging faulty code. LINQ makes it easy to query collections and that's why I like it a lot. Today is friday and weekend is coming. Let's relax and have some fun on me. Here's one proof how n00b I can...

Luís just broke the news on our LINQ with C# book. I was honored with the invitation from Luís to write this book with him for FCA , for which he has already published a few books [ ^ ] [ ^ ] [ ^ ] before. This will be an entry level book in Portuguese targeted to anyone wanting to learn LINQ with C#...

I’ve written a few posts about LINQ to SQL and am generally a big fan of the technology (even with its weaknesses) since it’s very productive.  After creating a custom DataContext object using the LINQ to SQL designer (or one created by hand) I always ensure that the object is wrapped in a “using...

In the past I presented another possible use for the using keyword: as hints on LINQ . I’ve been giving some thought about this lately and refined my proposal. var q = from person in personCollection using MyEnumerableExtensions group person by person.LastName into g using new MyOtherComparer () orderby...

(This was pointed out to me by Frans Bouma and explained by Jon Skeet ) Imagine you have this set of classes: public class A { public virtual string P { get { return "A" ; } } } public class B : A { } public class C : B { public override string P { get { return "C" ; } } } And this class: public static...

Baseline Road ( map ) Tempe, Arizona 85283 It looks like there are a lot of great talks scheduled covering everything from iPhone...

I'm working with a database table that has a RowVersion field defined as a TimeStamp data type.  The TimeStamp field is there to add concurrency into the application to ensure a row hasn't changed while a user is trying to update or delete it.  When the TimeStamp field value is queried and...
