Set DataContext in XAML

Question

I have this simple application that adds some items to a combobox:

public partial class Window1 : Window
    {
        private ObservableCollection

        

Answer 1

I believe the DataContext in this scenario is implicit and does not have to be set since you are using the code behind. If you were using MVVM you would add a reference to that folder and class inside of you XAML markup and set the resource key equal to a value that can then be declared as the DataContext inside of a child elements DataContext property. But in your case (since you are not using MVVM) you shouldn't have to do that.
