Last month we released the Beta of VS 2010 Service Pack 1 (SP1). You can learn more about the VS 2010 SP1 Beta from Jason Zander’s two blog posts about it, and from Scott Hanselman’s blog post that covers some of the new capabilities enabled with it. You can download and install the VS 2010 SP1 Beta here . Last week I blogged about the new Visual Studio support for IIS Express that we are adding with VS 2010 SP1. In today’s post I’m going to talk about the new VS 2010 SP1 tooling support for SQL CE, and walkthrough some of the cool scenarios it enables. SQL CE – What is it and why should you care? SQL CE is a free, embedded, database engine that enables easy database storage. No Database Installation Required SQL CE does...
Earlier this week the data team released the CTP5 build of the new Entity Framework Code-First library. In my blog post a few days ago I talked about a few of the improvements introduced with the new CTP5 build. Automatic support for enforcing DataAnnotation validation attributes on models was one of the improvements I discussed. It provides a pretty easy way to enable property-level validation logic within your model layer. You can apply validation attributes like [Required], [Range], and [RegularExpression] – all of which are built-into .NET 4 – to your model classes in order to enforce that the model properties are valid before they are persisted to a database. You can also create your own custom validation attributes...
Do you like a big pile of source code? Well, there is an imperial buttload of source in the Visual Studio 2010 and .NET Framework 4 Training Kit . It's actually a 178 meg download, which is insane. Perhaps start your download now and get it in the morning when you get up. It's extremely well put together and I say Kudos to the folks that did it. They are better people than I. I like to explore it while watching TV myself and found myself looking through tonight. I checked my blog and while I thought I'd shared this with you before, Dear Reader, I hadn't. My bad, because it's pure gold . With C# and VB, natch. Here's an outline of what's inside. I've heard of folks setting up lunch-time study groups and going through...
You can learn a lot by reading other people's source code. That's the idea behind this series, " The Weekly Source Code ." You can certainly become a better programmer by writing code but I think good writers become better by reading as much as they can. I was poking around in the WebFormsMVP project's code and noticed an interesting pattern . You've seen code to get data from a database and retrieve it as an object, like this: public Widget Find(int id) { Widget widget = null; widget = (from w in _db.Widgets where w.Id == id select w).SingleOrDefault(); return widget; } This code is synchronous, meaning basically that it'll happen on the same thread and we'll wait around until it's finished. Now, here's...
There has been a lot of excitement in the community about the new ASP.NET MVC framework that is about to ship (literally any day now – announcement coming soon). As with anything new, people are also asking for more tutorials/samples/documentation that cover how to get started and build applications with it. Over the last few months I’ve been helping to contribute to an ASP.NET MVC book that Scott Hanselman, Rob Conery, and Phil Haack have been writing for Wrox. The book is now in production, and will be available to buy in stores soon (you can pre-order it on Amazon today). I wrote the first chapter of the book – which is a 185 page end-to-end tutorial that walks-through building a small, but complete, ASP.NET MVC application from...
