Finding and Sharing Extensions
You can download, install, and manage Visual Studio extensions by using Extension Manager, which is available on the Tools menu. You can also obtain extensions by going to websites such as the Visual Studio Gallery, or by getting them directly from other developers. For more information about how to find and install extensions, see Managing Extensions and Updates for Visual Studio.
You can also create extensions, wrap them in deployment packages, and share them with other developers by posting them on the Internet, posting them on a network share, or sending them by email. If you wrap an extension in a VSIX deployment package and upload it to the Visual Studio Gallery website, other developers can use Extension Manager to install it. For more information about VSIX deployment, see VSIX Deployment.
