# Aspose.Slides for OpenXML > Source: https://docs.aspose.com/slides/net/aspose-slides-for-openxml/ Updated: 2026-01-19 ## **What Is OpenXML?** OpenXML SDK is a .NET SDK from Microsoft in order to process Microsoft Office 2007 and above file formats. These file formats are basically zipped packages and the Open XML SDK for Office simplifies the task of manipulating Open XML packages and the underlying Open XML schema elements within a package. The classes in the Open XML SDK encapsulate many common tasks that developers perform on Open XML packages, so that you can perform complex operations with lines of code. Once you have installed the Open XML SDK 2.5, open your existing project or application in Visual Studio, or create a new project or application. Then, in your project or application, add references to the following components: - DocumentFormat.OpenXml - WindowsBase ## **Aspose.Slides for .NET** Aspose.Slides for .NET is a unique PowerPoint® management component that enables .NET applications to read, write and manipulate PowerPoint documents without using Microsoft PowerPoint. Aspose.Slides for .NET is the first and only .NET component that provides functionality to manage PowerPoint documents within your own applications. As with all Aspose .NET components, Aspose.Slides is written in managed C#, incredibly priced and lightning fast. ## **Aspose.Slides for OpenXML** ## **Introduction** The developers looking for file format libraries may need to walk through the features provided by the libraries available on the market. Mainly, two factors are considered when choosing an option: - Features - Efforts required to use the library If you are a .NET developer looking for faster,easy and light-weight file format library to process files, you may need to compare VSTO(Visual Studio tool for Office) with Aspose. In this case, this project will help you to compare features and code in both libraries. ## **System Requirements and Supported Platforms** ### **System Requirements** One or more of the following editions of Visual Studio Tools for Office: - Microsoft Visual Studio 2005 Tools for the Microsoft Office System - Microsoft Visual Studio 2005 Tools for the 2007 Microsoft Office System - Visual Studio 2008 Professional Edition - Visual Studio 2008 Team Suite Edition - One version of Microsoft Office: - Microsoft Office Professional 2003 SP1 - 2007 Microsoft Office system ### **Supported Operating Systems** - Windows 2000; Windows Server 2003; Windows Vista; Windows XP ### **.NET Framework Versions Supported** - only .NET framework 2.0 or greater. ## **Downloading** You can download the latest code at: - [Github](http://goo.gl/sZsbbu) - [Sourceforge](http://goo.gl/AWc3J3) - [Bitbucket](http://goo.gl/8B9p3b) ## **Installing** To open the project you need to download and install the latest version of Aspose.Slides for .NET from [here](http://www.aspose.com/.net/powerpoint-component.aspx) and include it in the project. ## **Support, Extend and Contribute** ### **Support** We offer free support.
