Visual Studio provides project templates you can use to create VSTO Add-ins for Microsoft Office PowerPoint. You can use VSTO Add-ins to automate PowerPoint, extend PowerPoint features, or customize the PowerPoint user interface (UI).
For more information about VSTO Add-ins, see Getting Started Programming VSTO Add-ins and Architecture of VSTO Add-ins. If you are new to programming with Microsoft Office, see Getting Started (Office Development in Visual Studio).
Applies to: The information in this topic applies to VSTO add-in projects for PowerPoint. For more information, see Features Available by Office Application and Project Type.

The PowerPoint object model exposes many types that you can use to automate PowerPoint. These types enable you to write code to accomplish common tasks:
Programmatically create and format presentations.
Add or remove slides from presentations.
Add or change shapes on a slide.
To access the PowerPoint object model from an VSTO Add-in, use the Application field of the ThisAddIn class in your project. The Application field returns a T:Microsoft.Office.Interop.PowerPoint.Application object that represents the current instance of PowerPoint. For more information, see Programming VSTO Add-Ins.
When you call into the PowerPoint object model, you use types that are provided in the primary interop assembly for PowerPoint. The primary interop assembly acts as a bridge between the managed code in the VSTO Add-in and the COM object model in PowerPoint. All types in the PowerPoint primary interop assembly are defined in the N:Microsoft.Office.Interop.PowerPoint namespace. For more information about primary interop assemblies, see Office Solutions Development Overview (VSTO) and Office Primary Interop Assemblies.
For complete information about the PowerPoint object model, you can refer to the PowerPoint primary interop assembly (PIA) reference and the VBA object model reference.
The PowerPoint PIA reference documentation describes the types in the primary interop assembly for PowerPoint. This documentation is available from the following location: PowerPoint 2010 Primary Interop Assembly Reference.
For more information about the design of the PowerPoint PIA, such as the differences between classes and interfaces in the PIA and how events in the PIA are implemented, see Overview of Classes and Interfaces in the Office Primary Interop Assemblies.
The VBA object model reference documents the PowerPoint object model as it is exposed to Visual Basic for Applications (VBA) code. For more information, see PowerPoint 2010 Object Model Reference
All of the objects and members in the VBA object model reference correspond to types and members in the PowerPoint primary interop assembly (PIA). For example, the Presentation object in the VBA object model reference corresponds to the T:Microsoft.Office.Interop.PowerPoint.Presentation type in the PowerPoint PIA. Although the VBA object model reference provides code examples for most properties, methods, and events, you must translate the VBA code in this reference to Visual Basic or Visual C# if you want to use them in a PowerPoint VSTO Add-in project that you create by using Visual Studio.
You can modify the UI of PowerPoint in the following ways.
For more information
Create a custom task pane.
Add custom tabs to the Ribbon.
Add custom groups to a built-in tab on the Ribbon.
For more information about customizing the UI of PowerPoint and other Microsoft Office applications, see Office UI Customization.
