Article Description:
With the release of Silverlight 4 two new interfaces are now available including IDataErrorInfo and INotifyDataErrorInfo. In this post I'll walk through the process of using the IDataErrorInfo interface which provides a more simplistic way to validate data and provide end users with notifications. Let's start by taking a look at the interface's members

Comments:
Nice intro to IDataErrorInfo and how to use it in SL4. With this interface you can implement complex validations (the ones that cannot be implemented by DataAnnotations).

Article Description:
I must use the clipboard hundreds of times a day. Business applications need clipboard access. Silverlight 3 only provided clipboard access in the form of a couple of built-in controls ( like TextBox ) providing copy/paste automatically like most TextBoxes in the world already do.
But in Silverlight 4 this is expanded to allow for more complete clipboard access.

Comments:
Quick reading, to check the new clipboard access features implemented on Silverlight 4.

Article Description:
I recently wrote an article that demonstrates how to use the DataForm and validate data entry in Silverlight using the DataAnnotations. One of the pet peeves I have with the validation is that it throws in exception in the setter of your public property. Putting my disagreements with that aside for a second, it causes a major inconvenience when debugging the application. For example, when running the application that uses the DataAnnotations and one of the conditions is violated, the debugger will catch the validation exception and break into the code. The desired behavior is that the debugger will not break into the code since I really just want to see the validation information on screen.
|
Comments:
Data Annotations are quite powerful, but is annoying when you are debugging and you get Visual Studio debugger hitting validation violations and unhandled exceptions, here you will find trick to disable that tracking.

Article Description:
The common technique many developers use to debug Silverlight Out of Browser applications is to attach the debugger to the SLLauncher.exe process. However, there is a another way to debug installed OoB apps. Attaching to the process does not allow you to catch and debug any startup code however this technique below does allow you to do so.

Being Silverlight developer means that we are also kind of web developers. From this point of view, we also have to think about the web traffic that our applications generate. We need to reduce it as much as possible. So basically we need to reduce the size of the application's output - the .xap file.

Comments:
Nice XAP optimization article... always check for good practices and avoid the "localhost" effect.

SketchFlow is a great addition to Blend, but I was missing the ability to create quick mockups of user interfaces. I’m a huge fan of productivity tools such as Balsamiq, and I was sorely missing its ease and speed in SketchFlow.

Comments:
Great stuff, addon to add powerful balsamiq features to Sketchflow (quite easy to drop controls and add data).

Article Description:
An article was published at JupiterJS.com (titled “JavaScript vs Silverlight”) arguing that JavaScript is better than Silverlight. Unfortunately, there is no way to post comments on that page (weird, really) so I decided I would post my answer here.

Comments:
Interesting post comparing Silverlight with Javascript, highlighting weak and stron points, a nice read (also nice to read the article reffered that only covers the javascript part)
Good to read both points of views
