SonarLint is a Visual Studio 2015 and 2017 extension that provides on-the-fly feedback to developers on new bugs and quality issues injected into .NET code. SonarLint for Visual Studio is based on and benefits from the .NET Compiler Platform (aka "Roslyn") and its code analysis API to provide a fully-integrated user experience in Visual Studio 2015 and Visual Studio 2017. SonarLint is free, open source, and available in the Visual Studio Gallery.To provide feedback (request a feature, report a bug etc.), simply create a GitHub Issue. Alternatively you can use SonarQube Google Group or StackOverflow with the tag sonarlint-vs.
