VS 2010 SP1 and SQL CE
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 …
Class-Level Model Validation with EF Code First and ASP.NET MVC 3
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 enforc…
Announcing Entity Framework Code-First (CTP5 release)
This week the data team released the CTP5 build of the new Entity Framework Code-First library. EF Code-First enables a pretty sweet code-centric development workflow for working with data. It enables you to: Develop without ever having to …
The Weekly Source Code 56 – Visual Studio 2010 and .NET Framework 4 Training Kit – Code Contracts, Parallel Framework and COM Interop
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…(read more)
Using EF “Code First” with an Existing Database
Last month I blogged about the new Entity Framework 4 “code first” development option. EF “code-first” enables a pretty sweet code-centric development workflow for working with data. It enables you to: Work with data without ever having to open a designer or define an XML mapping file Define model objects by simply writing “plain old classes” with no base classes required Use a “convention over configuration” approach that enables database persistence without explicitly configuring anything In my initial blog post I introduced EF “code-first” and demonstrated how to use the default EF4 mapping conventions to create a new database. These default conventions work very well for new applications, and enable you to avoid having…(read more)
Entity Framework 4 “Code-First”: Custom Database Schema Mapping

The Weekly Source Code 52 – You keep using that LINQ, I dunna think it means what you think it means.
Remember good developers don't just write source code, they also READ it. You don't just become a great poet by writing lots of poems. Read and absorb as well. Do check out the Source Code category of my blog here , there's (as of today) 15 pages of posts on Source Code you can check out. Recently my friend Jonathan Carter (OData Dude, my name for him) was working with a partner on some really weird stuff that was happening with a LINQ to SQL query. Remember that every abstraction sometimes leaks and that the whole port of an abstraction is "raise the level" so you don't have to worry about something. Plumbing is great because it abstracts away water delivery. For all I know, there's a dude with a bucket who runs…(read more)
The Weekly Source Code 51 – Asynchronous Database Access and LINQ to SQL Fun
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…(read more)
