Add Method

We want to be able to add items to and remove items from the collection.

In the next step, we'll add a TextBox and a Button to let the user add new To-Do items.

<dot:TextBox Text="{value: NewItem}" />
<dot:Button Click="{command: Add()}"
            Text="Add Item" />

However, we need to do something else first.

Tasks

Let's write the adding logic first.

• Add a string property called NewItem to the ViewModel.
• Inside the Add method, create a new ToDoItem object and initialize its Text property to NewItem. Then add the instance to Items.
