MVVM Framework Explorer update and top MVVM Frameworks

Silverlight, Windows Phone, WPF, ,

A couple of days ago I received an email from Geert van Horrik, a developer working on a new MVVM Framework called Catel. Geert asked me to update my MVVM Framework Explorer app in order to include his new framework. Here is the resulting updated app (click to launch):

Besides adding this new framework, I updated the download count for each framework, which allowed me to do some statistics. Here are the download progression for the most popular MVVM frameworks between July 2010 and January 2011:

Attributes-based validation in a WPF MVVM application

.Net, CodeProject, WPF, , ,

Today, I’m proud to share with you my very first article available on CodeProject. This article presents a technique which can be used in order to add validation in a WPF MVVM application based on attribute. Basically, it means that you can write validation logic like that (notice the attribute associated to this property):

[Required(ErrorMessage = "Field 'FirstName' is required.")]
public string FirstName
{
    get
    {
        return this.firstName;
    }
    set
    {
        this.firstName = value;
        this.OnPropertyChanged("FirstName");
    }
}

Of course the article comes with a nice demo application:
