WPF

The WPF team recently released a new Ribbon completely in WPF (no wrapper around native code). So you can play with your XAML to give it the look and contextual menus you want!

Microsoft has just unveiled LightSwitch, a tool for developing business applications without having to touch the code. Jason Zander provides an excellent introduction on his site.

There will be a template for C# and VB. At first glance, the generated application seems to run on WPF for the Desktop version, and probably Silverlight or XBAP for the web version.

The beta will be available on August 23rd.

Stay tuned

I encountered a situation while developing a WPF application that used the ObservableCollection class. Here is the description:

Problem:

A collection of items that contains several items (which themselves implement the INotifyPropertyChanged interface). I need to perform certain calculations: total items to be completed, total completed items, remaining items, etc. But when one of these items changed status and became completed, it was impossible to push the information (push) to a higher level.

For some time now, I have had the chance to experiment with PRISM and I really like what it brings to the table. But I also use some Telerik controls for WPF, and after doing some research, I noticed that Telerik has included in its documentation some elements about PRISM.
