Put simply, we don't do that in WPF. Instead, you should add a reference to the other project, add a using declaration and then instantiate an object from that class. Then (assuming that your method returns a collection of some sort) you should set the output of the method to a collection property that you then data bind to the ItemsSource property.

Here's a very basic example:

private ObservableCollection<int> numbers = new ObservableCollection<int>();
public ObservableCollection<int> Numbers
{
    get { return numbers; }
    set { numbers = value; NotifyPropertyChanged("Numbers"); }
}

...

Numbers = new YourClassFromOtherProject().GetData();

...

<ItemsControl ItemsSource="{Binding Numbers}" ... />
