Note
Var:ProductName 2026 Release will also support a new plugin system. Check back for details on the new plugin system when it becomes available.
This section describes how to build and deploy third-party plug-ins for Var:ProductName. For more information on building specific types of plug-ins, refer to the relevant SDK documentation.
Var:ProductName exposes various public APIs that allow you to extend the application by building plug-ins that integrate with the core application and provide additional features and functionalities. Third-party developers can build these plug-ins using the Var:ProductName SDK and deploy them into an existing Var:ProductName installation. This section focuses on third-party plug-in development and deployment.
Since Var:ProductName is a Microsoft .NET application, develop third-party plug-ins using Microsoft .NET Framework 4.8. The Var:ProductName SDK includes Visual Studio project templates that provide a quick start for creating various types of plug-ins. For more information, see Building a plugin.
Once you build a third-party plug-in, you can easily deploy it for use with Var:ProductName. See Plug-in deployment for details on the deployment process.
While the standard project templates included in the Var:ProductName SDK allow you to create a basic plug-in package for distribution to end-users, you might need to add additional assemblies or other files to the plug-in package.
To do so, edit the pluginpackage.manifest.xml file that resides in the Visual Studio project folder.
