Catel.MVVM

The last few years, MVVM has become the number one pattern to write applications using WPF and other XAML related platforms. The actual pattern is very simple, but there are some flaws and questions lots of MVVM users have, such as:

This part of the documentation explains all about the MVVM framework included with Catel. The MVVM framework that ships with Catel has the following characteristics and features:
