Beginning March 1, 2022, SonarLint for Visual Studio 2017 will no longer be supported. This means that there will not be any new updates to this version. We encourage users to take advantage of the latest enhancements by updating to SonarLint for Visual Studio 2019 or 2022.
SonarLint: Your first line of defense for quality and secure code
SonarLint helps you detect and fix Bugs, Code Smells, and Security Vulnerabilities in-IDE.
It supports C#, VB.NET, C, C++, JS, and TS. The extension highlights coding flaws on the fly and provides clear guidance to fix issues before code is committed.
What is SonarLint
SonarLint is a Free and Open Source IDE extension that identifies and helps you fix Code Quality and Code Security issues as you code. Analogous to a spell checker, SonarLint squiggles flaws and provides real-time feedback and clear remediation guidance so you can deliver clean code from the get-go.
SonarLint for Visual Studio is more than your average linting tool.
SonarLint provides Visual Studio developers a comprehensive in-IDE solution for improving the quality and security of the code they deliver.
Get Started with SonarLint
After you download SonarLint, simply open a project, start coding and SonarLint will start analyzing your issues.
You can also check out the SonarLint documentation here.
SonarLint for Teams
SonarLint works great as a standalone tool but you can take it to the next level by connecting it with SonarQube or SonarCloud. SonarQube and SonarCloud analyze Pull Requests and branches in your DevOps platform (BitBucket, GitHub, Microsoft Azure, GitLab) and perform non-disruptive code quality and security checks to reliably track your codebase health.
The 'connected mode' configuration ties SonarLint's continuous Code Quality and Code Security analysis from IDE to the entire CI/CD workflow and back again to your IDE.
