LINQ

Channel9Spain — Wed, 04 Nov 2009 01:36:00 GMT

Jose Murillo, especialista en Soluciones de Desarrollo de Microsoft Ibérica, nos cuenta qué es LINQ (Language INtegrate Query). Si no habéis oído hablar de LINQ nos referimos al lenguaje de consultas integrado que supone la mayor novedad del .NET Framework 3.

LinQ nos permite utilizar la misma sintaxis para consultar diferentes fuentes de datos (Objetos en memoria, Bases de Datos y orígenes XML). Como en todos nuestros webcast, Jose nos mostrará de forma práctica y básica el uso de esta nueva tecnología.

Navigating through the hypes, Software architectures and patterns to help avoiding your projects to crash. (Dutch)

Matthijs Hoekstra — Fri, 04 Sep 2009 13:01:00 GMT

When it comes to .Net software development, more and more frameworks enter the market. Both from Microsoft and in open source. Just think of all the very useful frameworks, such as ASP.NET MVC, Castle, WF, Entity Framework, Unity, Linq2SQL, ADO.NET Data Services, WCF, nHibernate, Spring.NET, CSLA, NUnit, Enterprise Library or ADF. Once a project chooses to apply one or more frameworks, trouble begins. What if you require additional features that aren’t implemented in the framework? What if you decide that another framework would have been better and want to switch halfway your project? What if the author of your favorite open source framework suddenly stops developing? What if the framework contains bugs or omissions? And what if a new version of the framework is released that is implemented totally different? These and many more everyday problems will cause your project to come to a halt, or at least make you perform serious refactoring. During this highly interactive talk Sander Hoogendoorn, principal technology officer at Capgemini, chief architect of Capgemini’s agile Accelerated Delivery Platform, and member of Microsoft’s Visual Studio Advisory Board, will demonstrate pragmatic software architectures and patterns that will help your projects to stay away from framework problems, and how to keep your code independent of framework choices. In his well known slightly ironic style Sander will present different models of layered architectures, and explain and use bridge patterns, managers, dependency injection, descriptors, and layer super-types. Of course, the speaker will illustrate these insightful patterns with lots of demo’s and (bad) code examples using blocks from Microsoft’s Enterprise Library, nHibernate, Log4Net, and the Entity Framework. Delegates will benefit from this talk by learning how to improve the structure and quality of their software architecture and code, and how to avoid the pitfalls of applying frameworks to .Net software development.

Deze video is opgenomen tijdens de DevDays in Den Haag in juni 2009. DevDays is het grootste evenement op het vlak van softwareontwikkeling en -architectuur in Nederland. Duizenden development professionals bezoeken dit jaarlijkse evenement om in twee dagen weer volledig op de hoogte te zijn van alle ontwikkelingen op hun vakgebied.

LINQ Language Deep Dive with Visual Studio 2008

Beth Massi — Wed, 22 Jul 2009 05:13:00 GMT

Ever wonder what really happens when you write a simple LINQ query? A lot of new language features went into the compilers in Visual Studio 2008 to make LINQ work. In this interview I sit down with Jonathan Aneja, a Program Manager on the Visual Basic Compiler team, who dives deep into these features like Type Inference, Anonymous Types, Lambda Expressions, Expressions Trees, and more. He explains what's actually happening behind the scenes and all the work the compiler is doing for you when you write a LINQ query. My head almost explodes at the end but I learned a lot of important concepts. ;-)

Check out Jonathan on the VB Team Blog.

Enjoy,

Expert to Expert: Erik Meijer and Roger Barga - Introduction to Dryad and DryadLINQ

Charles — Thu, 16 Jul 2009 16:43:00 GMT

Microsoft Research recently announced the availability, under Academic Licensing, of Dryad, an infrastructure which allows a programmer to use the resources of a computer cluster or a data center for running data-parallel programs. A Dryad programmer can use thousands of machines, each of them with multiple processors or cores, without knowing anything about concurrent programming.

DryadLINQ is the managed high level programming abstraction used to compose Dryad vertex topology graphs that the Dryad infrastructure uses to partition parallel computations. Here, Erik Meijer and Dryad team member Roger Barga discuss Drayad and DryadLINQ at a high level so that most of us can understand the implications, history and future of Dryad. This is an introductory piece. Erik and I will dive deep into Dryad with one of the scientists behind it in the second part of this Expert to Expert mini series on Dryad. UPDATE: The Going Deep episode on Dryad is now live.

Enjoy! This is incredible and important technology for simplifying the inherent complexity of distributed computation in the cloud. In essence, DryadLINQ enables a sequential programming experience over what will execute across potentially thousands of machines (depending upon the computational complexity of the program) concurrently. Much to learn here. Channel 9 will help teach.

Editorial note: When we discuss native code and the implementation of Dryad, the focus is on DryadLINQ not the Dryad infrastructure and low level vertex APIs, which are written in C++. Just to be clear...

Expert to Expert: Erik Meijer and Bart De Smet - LINQ-to-Anything

Charles — Wed, 15 Oct 2008 15:31:00 GMT

Welcome to the 100th episode of Going Deep! It's been a great ride so far and I hope you've been enjoying the show over the years. For this momentous occasion, meet Bart de Smet, a software engineer extraordinaire on the WPF team who spends his free time blogging (what an incredible wealth of truly useful technical information to be found on Bart's blog!) and creating custom LINQ providers. In fact, Bart is probably the world's most prolific LINQ provider creator, from LINQ-to-MSI to LINQ-to-Simpsons! How does he do it???

Of course, in this special episode who better to have involved in this LINQ'ified conversation (with lots of whiteboarding) than LINQ co-creator, programming languages designer, fundamentalist functional programming high priest and Channel 9 star Erik Meijer? In fact, given that this is an Expert to Expert Going Deep, Erik co-conducts the interview (and he's great at it as usual!). Nothing better than watching and listening to two experts geeking out at a whiteboard!

What makes LINQ so readily "providable"? How does Bart concoct his LINQ provider magic? Here, we dig into the details that enable LINQ-to-Anything.

Tune in. There's a lot of very useful technical information here (which I hope is the case for all 100 Going Deep episodes).

Enjoy and thanks for watching!
