    <p>I got confused after reading the documentation of Unity framework. <a href="http://msdn.microsoft.com/en-us/library/ff648512.aspx" rel="nofollow">link</a> </p> <p>I'am writing a WPF application which will search for some devices.<br> Below my code from my main Window. As you can see, now i'am still declaring UnitOfWork and DeviceService inside my main Window. I want to replace this code by applying Dependency Injection. At the same time i would also inject my viewmodel inside my main window. </p> <pre><code> public Window1() { InitializeComponent(); UnitOfWork myUnitOfWork = new UnitOfWork(); DeviceService dService = new DeviceService(myUnitOfWork); _vm = new DeviceViewModel(dService); this.DataContext = _vm; _vm.SearchAll(); } </code></pre> <p>I gave a try in below code but i failed in setting the container. The real question is how should i start? Do i need to completely change the stucture of my program?</p> <pre><code>public partial class App : Application { protected override void OnStartup(StartupEventArgs e) { base.OnStartup(e); IUnityContainer container = new UnityContainer(); UnitOfWork myUnitOfWork = new UnitOfWork(); container.RegisterInstance&lt;UnitOfWork&gt;(myUnitOfWork); Window1 w1 = new Window1(); w1.Show(); } } </code></pre> <hr> <p>I went trough the suggested tutorial. It is still not clear for me on how i should configure the property injection.</p> <p>My viewmodel should be injected in the Window 1 class, so i assume that i have to create a dependency property.</p> <pre><code> private DeviceViewModel viewModel; [Dependency] public DeviceViewModel ViewModel { get { return viewModel; } set { this.DataContext = value; } } </code></pre> <p>How can i inject my viewmodel into window 1, knowing that DeviceViewModel has dependency on DeviceService and again on UnitOfWork ?</p> <pre><code>//CONSTRUCTOR public DeviceViewModel(DeviceService service) { Service = service; SearchCommand = new SearchCommand(this); } private UnitOfWork myUnit; public DeviceService(UnitOfWork unit) { myUnit = unit; } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
