I know difference between Invoke and BeginInvoke :) I ll try to use EventLog to understand what happens...

In case when I use BeginInvoke() then foreach doesn't ends because I get exception after first result returned because it's navigation properties are NULLs and I am trying to use them. I think that I will have to solve problem of thread safety after I understand why navigation properties are NULL in case of BeginInvoke()

I remove TwoWay binding from SelectedIndex to prevent changes in DataContext. I have added following code that is called each time DataContext changed:
for (int i = 0; i < Tabs.Count; i++)
{
if (Tabs[i].IsSelected)
{
SelectedIndex = i;
OnPropertyChanged("Tabs");
OnPropertyChanged("SelectedIndex");
return;
}
}

SelectedIndex=0 (first tab), but NOTHING IS SELECTED!

I have tried force OnPropertyChanged("SelectedIndex") after DataContext's changed. Doesn't help. I select any Tab and begin change DataContext's, then while this process somehow SelectedIndex = -1...I just cant understand how...Seems that DataContext is not disconnected with another ListBoxItem where TabControl doesnt't has SelectedItem. And thanks to TwoWay binding, -1 from another ListBoxItem binds to DataContext and then to current TabControl

You are right, main DataContext contains another DataContext's. But Header and Data (from that contexts) are binded correctly. Problem is only with SelectedItem. I have tried to add SelectedIndex into main DataContext and create TwoWay binding with TabControl.SelectedIndex, but it doesnt help

- The type or namespace name 'BinaryReader' could not be found .......
- The type or namespace name 'FileStream' could not be found ........

if namespace not found, place cursor on missed word and press Alt+Shift+F10. If it is available on any available namespace then VS will show popup with this namespace.
