Last Friday while having a discussion on various LINQ standard query operators the topic of expressing T-SQL CASE statement in LINQ came up. The most obvious solution to this is using the ternary operator as shown below: (more)

Using LINQ and reflection to find matching properties of objects
As a side product of some experiments I wrote simple LINQ query that matches properties of two objects and returns these properties as list. The code I wrote is pretty simple and I packed it for you as method. (more)

Introduction to the Reactive Framework Part III - Matthew Podwysocki's Blog
In my previous post in the Introduction to the Reactive Framework series, I discussed the duality between the IEnumerable/IEnumerator and IObservable/IObserver and how that enables us to generalize the ideas from LINQ to Objects to LINQ to Observables/Events.  After the last post, I was asked how we go from events to Observables, so let’s tackle that in this post. Before we get started, let’s get caught up to where we are today:Part I – IntroductionPart II – Duality of Enumerable/ObservableFrom Events..... (more)

Understanding LINQ and LINQ to SQL (and EF)
Understanding LINQ and LINQ to SQL (and EF)   Back to basics for this post. Developers often throw around the word LINQ when talking about a number of different technologies. Now that I have been comfortably using a wide variety of LINQ technologies for a fair amount of time, I’m now able to convey some of the key differences that are critical to using LINQ technologies efficiently. I’m also using this as a foundation and reference for some exciting upcoming post... (more)

an Open Source Utility that Automatically Create Data Transfer Objects based on LINQ to SQL Data Classes - Shahar Gvirtz's Weblog
An Open Source Utility that Automatically Create Data Transfer Objects based on LINQ to SQL Data Classes Few weeks ago I posted in my Hebrew blog a post about using Data Transfer Objects to work with LINQ to SQL and ADO.NET Entity Framework (that currently both of them doesn’t support working with POCO). One of the comments I got was that using DTO’s takes twice the time than not using them. That’s because you have to write DTO class for each entity and you also have to write  method in the DTO cla... (more)
