Dragging-and-dropping controls
It is highly recommended that you have a good knowledge of the XAML markup language and some experience practicing it. Nevertheless, if you intend to make a rapid prototype or just need to begin developing immediately, you can use the drag-and-drop controls from the toolbar directly in to the form (as in a WinForms application).
You can also edit the features of a control by accessing the Properties window as shown in the following screenshot:
In order to achieve a higher control over the windows layout (with the aim to, for example, achieve an optimal disposition of the controls in different resolutions), we suggest learning the XAML markup language or using Expression Blend, which is a tool for designers (and developers).
