# About the pre 23.4 Form experience

To connect and share data between UiPath Studio, UiPath Assistant, and UiPath.Form.Activities, the package uses an internal **Data Connector Mechanism**.

To generate schemas from NuGet Packages or from custom data, including user-defined data types in UiPath Data Service, the Form activity package uses a built-in schema generator logic.

The **UiPath Form Designer** found in the activity package is a customized implementation of the [form.io](https://www.form.io/) engine that provides a drag and drop form builder experience in Studio. The **UiPath Form Designer** functionality complies with internal security requirements.

## CefSharp Dependencies

* **UiPath.Form.Activities** version **1.1.8** is compatible only with versions from **4.10.2** to **4.12.0** included, if used in the same workflow.
* **UiPath.Form.Activities** version **1.1.11** is compatible only with versions higher than or equal to **4.13.0**, if used in the same workflow.

## Prerequisites

To use the old Form experience:

* Install **Form.Activities** versions **2.0.5** or lower.
* In UiPath Studio, version **2021.4**, install UiPath.Form.Activities **v1.1.11+**. Otherwise, when you open the **UiPath Form Designer**, it does not hold focus and you cannot interact with the Studio UI elements.
* Install NET Desktop Runtime 5.0 to use the UiPath.Form.Activities versions **2.0.1-preview** and lower.
