In the Entity Framework we can easily enable lazy loading of navigation properties by marking them as virtual. This however applies only to properties that reference other related entity type. The framework does not support lazy loading of scalar or primitive properties. But there is a trick to fill this lack quite easily.
Last time I showed a simple way of using application settings in our wpf application. This time I would like to present you my way of testing Properties.Settings, or rather mocking it in our application tests.
