+# Add a control (Windows Forms .NET)
+
+Most forms are designed by adding controls to the surface of the form to define a user interface (UI). A *control* is a component on a form used to display information or accept user input.<!-- TODO For more information about controls, see [Forms overview](..\forms\overview.md). -->
+
+The primary way a control is added to a form is through the Visual Studio Designer, but you can also manage the controls on a form at run time through code.
+
+[!INCLUDE [desktop guide under construction](../../includes/desktop-guide-preview-note.md)]
+
+## Add with Designer
+
+Visual Studio uses the Forms Designer to design forms. There is a Controls pane which lists all the controls available to your app. You can add controls from the pane in two ways:
+
+### Add the control by double-clicking
+
+When a control is double-clicked, it is automatically added to the current open form with default settings.
+
+:::image type="content" source="media/how-to-add-to-a-form/toolbox-double-click.gif" alt-text="Double-click a control in the toolbox on visual studio for .NET Windows Forms":::
+
+### Add the control by drawing
+
+Select the control by clicking on it. In your form, drag-select a region. The control will be placed to fit the size of the region you selected.
+
+:::image type="content" source="media/how-to-add-to-a-form/toolbox-drag-draw.gif" alt-text="Drag-select and draw a control from the toolbox on visual studio for .NET Windows Forms":::
+
+## Add with code
+
+Controls can be created and then added to a form at run time with the form's <xref:System.Windows.Forms.Control.Controls%2A> collection. This collection can also be used to remove controls from a form.
+
+The following code adds and positions two controls, a [Label](xref:System.Windows.Forms.Label) and a [TextBox](xref:System.Windows.Forms.TextBox):
+
+:::code language="csharp" source="snippets/how-to-add-to-a-form/cs/Form1.cs" id="CreateControl":::
+
+:::code language="vb" source="snippets/how-to-add-to-a-form/vb/Form1.vb" id="CreateControl":::
