Visual Studio has a notification system that alerts you to various events, such as the following:
- An update is available for Visual Studio or a component in Visual Studio.
- An environment event that you might be interested in occurred.
Visual Studio notifies you when an update is available for Visual Studio itself or for any of the components that have been installed. It also provides notifications about certain kinds of events that occur in the Visual Studio environment. The notification icon is a flag in the upper right of the Visual Studio title bar; when the icon is red, it means that there is a problem with your license. When it's yellow there is a Visual Studio Product Update available for you to install. When it is "normal" or black you'll see messages that are informational or optional, such as crashes for which you might want to find a workaround. You can click on the icon to open the Notifications Hub and choose which ones to act on. You can choose to do a one-time dismiss on a notification, or always ignore a notification (by hovering over it) and Visual Studio will never show you that message again.
If you choose to always ignore a notification, Visual Studio will stop showing it. You can reset the list of ignored notifications in the Notifications, Environment, Options Dialog Box.
