Power Apps Component Framework overview and fundamentals

# Power Apps Component Framework Overview

Power Apps component framework empowers professional developers and app makers to create code components for model-driven and canvas apps. These code components can be used to enhance the user experience for users working with data on forms, views, dashboards, and canvas app screens.

## Key Capabilities

You can use PCF to:
- Replace a column on a form that displays a numeric text value with a `dial` or `slider` code component
- Transform a list into an entirely different visual experience bound to the dataset, like a `Calendar` or `Map`

## Important Limitations

- Power Apps component framework works only on Unified Interface and not on the legacy web client
- Power Apps component framework is currently not supported for on-premises environments

## How PCF Differs from Web Resources

Unlike HTML web resources, code components are:
- Rendered as part of the same context
- Loaded at the same time as any other components
- Provide a seamless experience for the user

Code components can be:
- Used across the full breadth of Power Apps capabilities
- Reused many times across different tables and forms
