return list of class object in WPF

I have a class as below.

namespace WpfApplication2
{
    class TaskItem
    {
        private string name;
        private string item;
        private string description;
        private int priority;
        public string Name
        {
            get
            { return name; }
            set
            { this.name = value; }
        }

        public string Item
        {
            get
            {
                return item;
            }
            set
            {
                this.item = value;
            }
        }
        public string Description
        {
            get
            {
                return String.Format("{0} {1}",name,item);
            }
        }
        public int Priority
        {
            get
            {
                return priority;
            }
            set
            {
                this.priority = value;
            }
        }

        public TaskItem()
        {


        }

    }
}

I want to return the list of this class object to my wpf application as below.

<WpfApplication2:TaskItem x:Key="taskItem"/>

After that I will bind this to ListBox. How could I return this list of class object? Please advise. Thanks.

Your xaml declaration is for a single TaskItem, not a collection. You need a collection to bind to the ItemsSource of your ListBox. See the notes on msdn about the limitations of a xaml only solution using ObservableCollection. You will probably want to create a list in code to bind to the ListBox, or create your own class that inherits from ObservableCollection and then create an instance of that class in you xaml instead.

Technically possible.. with something similar to this (Replace Observable collection with List and my:Person with your custom class). See also: Generics support was added recently to XAML

<Window>
    <Window.DataContext>
        <ObservableCollection x:TypeArguments="my:Person">
            <my:Person FirstName="Tom" LastName="Holiday" />
            <my:Person FirstName="Joan" LastName="Holiday" />
        </ObservableCollection>
    </Window.DataContext>
    …
</Window>

Have you tried to create a List<TaskItems> and set this as the DataContext ?
