What is VSTO?
VSTO, or Visual Studio Tools for Office, is a set of development tools available as a Visual Studio add-in. It allows developers to create extensions for Office applications using CLI compliant languages. VSTO enables the hosting of the .NET Framework Common Language Runtime (CLR) within Office applications and exposes their functionality through the .NET platform. This technology allows the use of Office application functionality and user interface constructs within .NET applications.
Originating as a successor to the developer editions of Office 2000 and Office XP, VSTO provides capabilities that surpass the previous COM add-in creations that were limited to Visual Basic or Visual C++. VSTO emphasizes stability and security in Office development and operates closely with Microsoft Office. It responds to events within the Office application and automates tasks through calls to the application's object model, utilizing the .NET Framework and primary interop assemblies to communicate with the application's COM components.
VSTO Add-ins, created with the Office developer tools in Visual Studio, are designed to be executed when an Office application is started by an end user. These add-ins are loaded in a separate application domain to ensure stability and are unloaded from memory upon the application's closure. Important components of VSTO Add-ins include the add-in assembly, registry entries, deployment manifest, application manifest, and the Visual Studio Tools for Office Runtime, which must be installed on end-user computers to run the add-ins.
