How to close User Control from its View Model
I created my UserControl like this:
MyUserCtrl myctrl = new MyUserCtrl() { DataContext = new MyViewModel()};
ControlCollection.Add(myctrl);
and i output it using this ItemsControl ItemsSource="{Binding ControlCollection}" to the View.
It's clean and nice but the problem is I don't know how can I close those UserControls that I opened.
And what if I just remove it to the collection. Thus the View Model will close too?

Do not assign a collection of UI elements to the ItemsSource of an ItemsControl. Instead, put the UI element in the ItemsControl's ItemTemplate and pass a collection of view model instances to the ItemsSource.
<ItemsControl ItemsSource="{Binding MyItems}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<local:MyUserCtrl />
</DataTemplate>
</ItemsCControl.ItemTemplate>
</ItemsCControl>
Add a view model item to the collection property in your "main" view model:
var item = new MyViewModel();
MyItems.Add(item);
To "close" a control, remove the appropriate item from the collection:
MyItems.Remove(item);
