What's wrong with
public partial class MainWindow : Window
{
public ObservableCollection<TabViewModel> Tabs { get; set; }
public ICollectionView TabsViewSource { get; set; }
public int CurrentIndex { get { return TabsViewSource.CurrentPosition; } }
I get
Inconsistent accessibility: property type 'System.Collections.ObjectModel.ObservableCollection' is less accessible than property 'TabsRendering.MainWindow.Tabs'
when i change the code to
public partial class MainWindow : Window
{
ObservableCollection<TabViewModel> Tabs { get; set; }
public ICollectionView TabsViewSource { get; set; }
public int CurrentIndex { get { return TabsViewSource.CurrentPosition; } }
It works. Whats wrong with the public
on the ObservableCollection

Make
TabViewModel
a public type too.Obviously, it doesn't make sense for a public property on a public containing-type to be of a type that is not public. How could the property present itself to external assemblies?
Your second sample works because, as a general rule, providing no accessibility modifiers means that the least applicable modifier is chosen as the default - in this case: private. Clearly, there are no consistency issues with declaring a private property of an internal (?) type.
