Until recently, creating a custom window style in Windows Presentation Foundation was quite a challenging task. You had to implement the window’s behavior from scratch. Resizing, moving and all other typically window related functionality had to be reinvented and reimplemented just because you wanted the window header bar to look different.
WPF has many rich features which facilitates making a great look&feel of the application. Unfortunately many of those features are cumbersome to implement and use when we develop in a Model - View – ViewModel architecture. In this post I will try to make you more familiar with visual states and how can we use them in our MvvM application.
FileTable is a great new feature in SQL Server 2012 which facilitates storing and working with unstructured blob data in SQL Server. Unfortunately is not yet supported in Entity Framework, so you cannot simply use FileTable in your entity model. But there is a workaround for this inconvenience, which I am going to show you in this post.
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.

Instead of creating many different instances of sub collection we can use the benefits of collection views.
