I'm proud to announce the Silverlight XP.net website. It is a web application where Silverlight Developers can post links to interesting information, controls, resources e.t.c. We invite you to submit your Silverlight resources.

Silverlight XP.net is a Silverlight 3.0 LOB application which uses a lot of the new techniques:

• .NET Ria Services
• Navigation Application (deeplinking + history)
• Search Engine Optimization (SEO)
• Behaviors

Silverlight XP was created by Loek van den Ouweland and me, and is currently at version 1.0. We plan to add a lot of features soon. We don’t have a feedback-function yet. Please drop comments about the website by mail.

Silverlight 3.0 has a great new feature called Behaviors. You can use them for a lot of things, one of them is to create a SNOW effect in a canvas. I know it is not yet Christmas but I like to be prepared. If you don't know what a behavior is or how to write them read first this blog post from Andrea Boschin.

You can download the sourcecode from here.

I finally found some time to test the beta of Visual Studio 2010. No problems found yet. It even supports a visual designer (Cider) for Silverlight projects. You can now use it to drag & drop controls from your toolbox, add rows/columns to a grid and set properties. Things which where only possible in Expression Blend.

I didn't go to the MIX09. Luckily Microsoft has published the sessions using high quality videos. Here are my favorites:

The Silverlight 3.0 Beta is out. Tim Heuer has written a great blog with all the new features. I have added the new SaveFileDialog to my Sudoku.

Now I can start to write a new Silverlight 3 training!.

Update 20 july 2009: Implemented Silverlight 3.0 RTW and moved the game to https://www.silverarcade.com/games/sonnemaf/sudoku 

I have created a LINQ extension method which can be used to Pivot an enumeration. Just like you can PIVOT a SQL Query in SQL Server.

The following example uses the Pivot() function to group Employees by Department and Function and aggregates the Salary using a SUM. The second example uses a different grouping and Counts the number of employees per group.

In order to make Cross Domain calls in Silverlight 2 applications, the server you wish to download data from must have a Policy File in place that allows access to your site. I have created a Silverlight Application in which you can check the content of the Policy Files (if exists).

I have created a new Silverlight 2 Control which is used in the Objectmap website. This control makes it easy for the customers of accounts to find their nearest object (branch, offices or sales outlet). They can also immediately retrieve dynamic directions to this location or link to a more info page.

Have a look at this demopage, sorry in Dutch only.

This control uses: Cross Domain WCF networking, Data Binding, Isolated Storage Settings, Google Maps API calls, Cross Domain HTML Bridge and Styling.

Dit is mijn eerste Silverlight 2 instructie video. In deze video toon ik hoe je een eenvoudige Hello World applicatie kunt opzetten met behulp van Silverlight 2 (RC0) en Visual Studio 2008 met Service Pack 1.

Download de HelloWorld.zip sourcecode. Zorg er wel voor dat je alle benodigde software geinstalleerd hebt.

I have created a RollMenu control in Silverlight 2 Beta 2. It uses an Xml file to configure the menu items.
