In my application, I have a fair amount of static data that lends itself to an XML file very well…it’s not enough data for a database solution, but too much to hard-code into the app. My goal was to store the info in an xml file and load it into an LINQ XElement. Then I could easily use LINQ queries to get the data I needed into my application. Unfortunately, it took a bit of messing around to figure out how to load this data from the file. Following are the steps I took.

The CTP4 release of the “EF Code-First” functionality provides a pretty nice code-centric way to work with data.  It brings with it a lot of productivity, as well as a lot of power.  Hopefully these two blog posts provides a glimpse of some of the possibilities it provides. 

A couple of days ago, we had posted a Link List of ASP.NET MVC, ASP.NET and jQuery Articles published on DotNetCurry in the last 6 months. This week, we will be covering the articles on Silverlight, .NET 4.0 and LINQ. This list should help you stay updated with the content you might have missed on this site. Most of the articles in this list are authored by Mahesh Sabnis and Suprotim Agarwal. 

Sometimes in Silverlight, you just want to get the largest possible webcam resolution. This snippet shows how to obtain that using LINQ.

As you all should be aware by now, the first release SL for the WP7 is not going to contain any structured data storage (SQL CE) functionality or LINQ data providers. However this fact should not preclude us from rolling out our own version. After all the LINQ to Objects is still supported and all what we need to come up with at this point is the ability to persist objects (or entities) to device's storage and then read from it

In my previous post I discussed creating the database and tables for the Silverlight HVP configuration data.  All that was great, and worked just dandy until it was time to get the data from the database server to the application running on the client.

“But,” I thought, “How hard can it be?”  I’ve done a few mini-tutorials… should be straight-forward… And it was… sorta.

What I will provide here is a brief overview of the Linq to Visual Tree API. The full sourcecode for this API is at the end of this article.

The Linq to Visual Tree API defines a number of extension methods on DependencyObject that provide mechanisms for navigating to other DependencyObject instances.

The DomainContext class allows the Silverlight client to access the Domain Service Class you created on the server side. A new DomainContext class is automatically generated on the client side for you when you create a new Domain Service.

In this WCF RIA Services post Fredrik Normén discusses how to dynamically build up a search string and pass it to the server side for execution.

I have seen questions about how to dynamically create search criteria when using WCF RIA Services and LINQ. So this post is about how you can dynamically create a criteria as a string on the client-side and pass it down to the server for execution.
