# Walkthrough: Create new WPF content on Windows Forms at design time

This article shows you how to create a Windows Presentation Foundation (WPF) control for use in your Windows Forms-based applications.

## Prerequisites

You need Visual Studio to complete this walkthrough.

## Create the project

Open Visual Studio and create a new **Windows Forms App (.NET Framework)** project in Visual Basic or Visual C# named `HostingWpf`.

> [!NOTE]
> When hosting WPF content, only C# and Visual Basic projects are supported.

## Create a new WPF control

Creating a new WPF control and adding it to your project is as easy as adding any other item to your project. The Windows Forms Designer works with a particular kind of control named *composite control*, or *user control*. For more information about WPF user controls, see <xref:System.Windows.Controls.UserControl>.

> [!NOTE]
> The <xref:System.Windows.Controls.UserControl?displayProperty=nameWithType> type for WPF is distinct from the user control type provided by Windows Forms, which is also named <xref:System.Windows.Forms.UserControl?displayProperty=nameWithType>.

To create a new WPF control:

1. In **Solution Explorer**, add a new **WPF User Control Library (.NET Framework)** project to the solution. Use the default name for the control library, `WpfControlLibrary1`. The default control name is `UserControl1.xaml`.

   Adding the new control has the following effects:

   - File UserControl1.xaml is added.

   - File UserControl1.xaml.cs (or UserControl1.xaml.vb) is added. This file contains the code-behind for event handlers and other implementation.

   - References to WPF assemblies are added.

   - File UserControl1.xaml opens in the WPF Designer for Visual Studio.

2. In Design view, make sure that `UserControl1` is selected.

3. In the **Properties** window, set the value of the <xref:System.Windows.FrameworkElement.Width%2A> and <xref:System.Windows.FrameworkElement.Height%2A> properties to **200**.

4. From the **Toolbox**, drag a <xref:System.Windows.Controls.TextBox?displayProperty=nameWithType> control onto the design surface.

5. In the **Properties** window, set the value of the <xref:System.Windows.Controls.TextBox.Text%2A> property to **Hosted Content**.

   > [!NOTE]
   > In general, you should host more sophisticated WPF content. The <xref:System.Windows.Controls.TextBox?displayProperty=nameWithType> control is used here for illustrative purposes only.

6. Build the project.

## Add a WPF control to a Windows Form

Your new WPF control is ready for use on the form. Windows Forms uses the <xref:System.Windows.Forms.Integration.ElementHost> control to host WPF content.

To add a WPF control to a Windows Form:

1. Open `Form1` in the Windows Forms Designer.

2. In the **Toolbox**, find the tab labeled **WPFUserControlLibrary WPF User Controls**.

3. Drag an instance of `UserControl1` onto the form.

    - An <xref:System.Windows.Forms.Integration.ElementHost> control is created automatically on the form to host the WPF control.

    - The <xref:System.Windows.Forms.Integration.ElementHost> control is named `elementHost1` and in the **Properties** window, you can see its <xref:System.Windows.Forms.Integration.ElementHost.Child%2A> property is set to **UserControl1**.

    - References to WPF assemblies are added to the project.

    - The `elementHost1` control has a smart tag panel that shows the available hosting options.

4. In the **ElementHost Tasks** smart tag panel, select **Dock in parent container**.

5. Press **F5** to build and run the application.

## Next steps

Windows Forms and WPF are different technologies, but they are designed to interoperate closely. To provide richer appearance and behavior in your applications, try the following:

- Host a Windows Forms control in a WPF page. For more information, see [Walkthrough: Hosting a Windows Forms Control in WPF](/dotnet/framework/wpf/advanced/walkthrough-hosting-a-windows-forms-control-in-wpf).

- Apply Windows Forms visual styles to your WPF content. For more information, see [How to: Enable Visual Styles in a Hybrid Application](/dotnet/framework/wpf/advanced/how-to-enable-visual-styles-in-a-hybrid-application).

- Change the style of your WPF content. For more information, see [Walkthrough: Styling WPF Content](walkthrough-styling-wpf-content.md).
