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:

Niagara's Validation DSL - First Pass

Introducing Project Niagara

Url: http://niagara.codeplex.com

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.

How Silverlight 3 Validation Works

SilverlightAs RIA Services is plodding towards a release, many people are looking at it to help them with validation of data in Silverlight. Using this validation in Silverlight 3 is pretty straightforward but there are some caveats.  I want to show you under the covers so you understand what is happening. In this first part of the series, let's look at what it means to use validation from the outside.

Back when Dynamic Data was being developed, a set of attributes was created to help tell the Dynamic Data folks about validation and other metadata so they could create smart scaffolds. These include:

Fall/Winter Silverlight Tour Schedule

Silverlight TourWe have made some adjustments in the Fall/Winter schedule for the Silverlight Tour. As Fall is often our busiest time of year, we decided to move some dates around to not conflict with the PDC and other conferences. Here is the new Schedule for the Silverlight Tour and the Advanced Silverlight Workshop:

Using Large Message Requests in Silverlight with WCF

SilverlightToday I was working with a client and ran into a problem I didn't expect. This particular problem had to do with Silverlight consuming a WCF Service. Sometimes WCF causes me to spew four letter words. There is a class of WCF problems that cause this: connection rejection. WCF has been designed to prevent common DDoS and other attacks that could cause servers to fail or at least not serve honest requests. To this end the default size of a request is quite small. In fact, its usually 64K in size. This size is fine for most every request but occassionally when a client wants to send a collection of things to the server this size is too small. But we'll get to that in a minute. First, some background...

This particular client has a large service that's been working for quite a while, then suddenly a single call he has was being rejected. The new service call he was making was sending back a list of a couple of hundred of POCO classes. He had been downloading large lists before so on the surface this should have worked. But it didn't. 

ADO.NET Data Services 1.5 Feature: Projections

SilverlightIf you've been following my blog, you should know that I am keeping a pretty close watch on ADO.NET Data Services. The team recently released a second CTP of the new version with some interesting features. This CTP has some pretty compelling additions, but I am going ot focus on one in particular.

I've been teaching and using ADO.NET Data Services for a long time and I like showing off exposing a LINQ-based provider (Entity Framework, NHibernate or others) to a Silverlight application. While ADO.NET Data Services does expose its API through a REST API, the magic for me is in its use in Silverlight. In case you haven't been following along, using the Silverlight client you can issue a LINQ query through the Silverlight client (though in fairness, the full power of LINQ is not supported in the client):

Silverlight Data Examples Have Been Updated!

Silverlight LogoIf you've never had the chance to visit my sister site (http://www.silverlightdata.com), now's a good time. I've updated my examples there to include my MVVM, Prism and Declarative UI examples (to go with the skinning/switchable Astoria example).  Take a look if you're doing Silverlight data-based applications.

Why Declarative UIs Are Important

Sketching a UIIf you're building Internet applications, you've probably been bombarded with lots of new technologies the last few years: Silverlight, Flex, ASP.NET MVC, jQuery, etc. While all of these technologies have their use-cases, many of them are pointing to something that is new and important.

Back from DevLink 2009!

DevLink

I had a great time at DevLink this year. Met up with lots of great heartland folks and had some really interesting conversations (about Ruby and F# specifically). If you missed DevLink this year, you missed a great conference. John Keller and company put on a great show (for only $100 conference fee). The .NET Rocks panel at the end of the three days capped off a great few days in Nashville.
