The team of silverlightshow.net announced today the first eco-contest. Obviously Silverlight is the focused technology but I really love the argument of the contest. The partecipants are invited to propose an application that will spread the word about climate change. After a failed of Copenaghen summit where the biggest and powerful countries have not been able to reach an agreement about the save of our planet there is for sure the need to embrace the cause and let people to be aware of this ...

When I wrote my article about local connections last year, I received many questions about writing application that communicate each other with this protocol. The reason for this request is that many people believe that Silverlight being a good platform for game developers due to its great graphical features and its simplicity, so a lot of them want to implement some kind of communication for on-line collaborative games. Local connections have not been made for this kind of usage because them a ...

The programming with the MVVM pattern often requires a proliferation of types because there are more Views that need a ViewModel than you might think. You can think that you need to associate a ViewModel only to simple blocks of your user interface, but while you are writing code you often understand that there are other cases where a ViewModel is required. As an example while populating a DataGrid binding simple entities to the grid is not good idea. A single row of a grid not only conta ...

Using a Ria Services Class library to collect DomainServices and DomainContexts in a solution is a good practice because everyone know the value of having classes separated in projects instead of having them in the web project. If you try to create this kind of project and then you add an Authentication Domain Service with the July 2009 CTP of Ria Services you will find two major drawbacks. First of all you will notice the generated code does not contains a RiaContext class. RiaContext is the ...

Since the first release of WPF the framework contains a component called CollectionViewSource. The CollectionViewSource allow developer to apply sorting, filtering and grouping to in-memory collections of objects. This component is very useful when small collections (up to hundreds of items) is loaded in memory and need to give a better experience to the user. Some months ago I provided an implementation of the CollectionViewSource for Silverlight 2.0. I worked hard to implement the componen ...
The paradigm behind REST services is very fascinating while it allow to manipulate resources over the network relying to Uri and Http Methods. For a few of you that are not aware of what REST means I suggest to think at the web because it is the more REST thing you know. When you are pointing your browser to a "resource" on the Internet, for example a product in a ecommerce website, you will write an Url in the browser that univocally identify the product. You now can imagine to use H ...
Some months ago, a couple of minutes after the first beta of Silverlight has been released, I've posted an article explaining how to configure the new Out of Browser feature in Silverlight 3.0. Now, just after the release of the final bits, I need to return back on the argument because something has changed during this time due to additional features and modification to the API I've explained. What has changed and What has been added. There is not any substantial change to the functi ...

Crawling the Internet there are many samples about how to write commands for the Composite Application Guidance, aka Prism v2.0. One of my favorites is the Erik Mork's podcast. I figure out the first time you see how many code you need, to write a working command you are really astonished. This also happened to me. But if you analyze the code you will see that the skeleton of a command is always the same, and you need to change only some names and types to have it working on different events. ...
