XBoxGames Databases for SQL Server 2005 and 2008

Silverlight Logo

As many of you who've been following know, I use a simple database of XBox game data as my example database. I usually remember to include it on the server project but in some examples its been forgotten. In other cases I've shipped with a 2008 version of the database instead of the 2005 version. To address this, I've uploaded .zip'd versions of both the 2005 and 2008 databases for anyone to use for any reason. This includes my RIA Services sample (which is using a SQL Server 2008 version) or my MVVM MSDN article sample which also uses a 2008 version. They include a MDF and a LDF.  If you have trouble attaching them to an existing database, try deleting the LDF file.  Go grab there here:

My Take on Brad Abrams' PDC RIA Services Talk.

Silverlight Logo

I've been looking at RIA Services for a long time now. I had the lucky pleasure of being given early access to the bits for what was then called "Alexandria". As most readers of this blog have read, I have had some issues with how RIA Services works. In the mean time Brad Abrams and the team have certainly responded and have made changes to the way that RIA Services works and much of it is for the better. I can see pretty simply how you can use RIA Services to build applications that are really architected well, with true separation of concerns. But there is blood in the water.

Silverlight Tour Now Includes Silverlight 4!


Silverlight TourNow that the big news of the Silverlight 4 Beta release is out, we can announce that we've been working hard to update our course to include Silverlight 4 material. Since Silverlight 4 is only in Beta (and no go-live license to boot), the Silverlight Tour will continue to teach Silverlight 3 and show the Silverlight 4 material in addition. This way whether you're building a short-term application you can get your Silverlight 3 needs met, but if you want to learn Silverlight for a long-term project, you can be sure that the Silverlight Tour will prepare you for the Silverlight of tomorrow.

Data Binding Changes in Silverlight 4

Silverlight LogoAs many of you don't know, I was previously known as "The ADO Guy" so of course my first jump into the new Silverlight 4 bits was to play with the new Data Binding changes. The improvements aren't dramatic but they do fill several key holes that existed in the earlier versions.  Let's take these changes one at a time.

Prior to Silverlight 4, in order to support data binding, the object had to derive from the FrameworkElement class which left out some key objects including Transformations.  Now data binding works on any object that derives from DependencyObject (which is most of the Silverlight 4 framework). You can see this in the example below.  (Note, you can also see the CompositeTransform which lets you set transformations of all four types in a single transform):

Silverlight 4 Beta Announced!


Silverlight LogoAs noted in Scott Guthrie's keynote early, Silverlight 4 is now in beta.  But what does that mean to you? Silverlight 4 Beta does not have a go-live license, so if you're building something to be released soon, I would stick with Silverlight 3. In contrast if you're working on a longer term project, especially a line-of business application, you'd be crazy to not look at Silverlight 4. Here are some of the major changes in this release:

Fun with CollectionViews


Silverlight LogoI've recently been looking at the PagedCollectionView class. For those who are not familiar with this class, it allows you to automatically show sections of a collection in a paged way (especially when paired with the PagerControl). There is a good example on MSDN here:

First Week of European Conference Tour


One week into my European Conference tour and I thought it was time to send you lot a update. My first stop was Sofia, Bulgaria to join the great folks at DevReach. I got in a couple of days early so I could relax and get my time change down.

My Favorite Silverlight Extensions APIs - Part 1


SilverlightAs some of you may know, I am a contributor to the SilverlightContrib open source project. Recently this project and the Silverlight Extensions open source project (also know as SLExtensions) decided to merge to create a single place for a lot of interesting functionality.

Choosing a Data Access Layer for Silverlight 3

SilverlightIf you're a regular reader of my blog, you'll probably remember my pithy blog post where I stated that "It all depends..." to the question "Which Data Access Should I Use for Silverlight 3?"  The reality is that much like the similar question I am confronted with at user groups for the past decade ("What data access should I use in my .NET app?"). The reasons for picking a strategy are wide and varied so I will not try to analyze all possible outcomes, but I think the different strategies need to be explained better.

The three major candidates in Silverlight 3 are Web Services (WCF/ASMX), ADO.NET Data Services and RIA Services.  In any situation, any of these will work. But they are suited to different styles and requirements. Here's the abridged differences between the stacks:

Introducing Project Niagara


The NiagaraThe goal of Project Niagara is to democratize the validation support. The project wants to help developers add validation support to ADO.NET Data Services as well as Web Services in Silverlight. In addition, it has the goal of allowing multiple ways to supply the validation metadata to the different data access strategies. As it is my opinion that there are scenarios where attributes are not the best idea.
