I’m in! How do I activate this in SonarLint?

First connect to a server via the SonarLint General Settings,
then bind the project under SonarLint Project Settings.

Out-of-the-box, SonarLint reports issues. You can go deeper and customize SonarLint to best align with your projects and work methods.

Fine tune your rules

In the SonarLint General Settings you can choose which rules should be active or not. You can also mute rules on-the-fly via a quick-fix option, or from the list of issues.

Analyze exactly what you want

You can tell SonarLint which files should not be analyzed. Just right-click on any file, or manage File Exclusions at project level (Configure SonarLint action).
