By default, a developer will receive notifications in the IDE when:
the Quality Gate status (failed / success / warning) of an open project / solution changes
a SonarQube analysis raises new issues introduced by this developer in an open project / solution
The activation or deactivation of notifications must be done individually, by each developer directly in SonarLint (on the IDE side).
Receiving notifications is configurable on the SonarLint side on a SonarQube server-by-server basis.
