# Getting Started with WinForms TabbedForm

This article shows how you can start using **RadTabbedForm**.

## Adding Telerik Assemblies Using NuGet

To use `RadTabbedForm` when working with NuGet packages, install the `Telerik.UI.for.WinForms.AllControls` package. The [package target framework version may vary](https://www.telerik.com/products/winforms/documentation/visual-studio-integration/available-nugets).

Read more about NuGet installation in the [Install using NuGet Packages](https://www.telerik.com/products/winforms/documentation/installation-and-upgrades/install-using-nuget) article.

> tip With the 2025 Q1 release, the Telerik UI for WinForms has a new licensing mechanism. You can learn more about it [here](https://www.telerik.com/products/winforms/documentation/licensing/license-key).

## Adding Assembly References Manually

When dragging and dropping a control from the Visual Studio (VS) Toolbox onto the Form Designer, VS automatically adds the necessary assemblies. However, if you're adding the control programmatically, you'll need to manually reference the following assemblies:

* **Telerik.Licensing.Runtime**
* **Telerik.WinControls**
* **Telerik.WinControls.UI**
* **TelerikCommon**

The Telerik UI for WinForms assemblies can be install by using one of the available [installation approaches](https://www.telerik.com/products/winforms/documentation/installation-and-upgrades/installing-on-your-computer).
