Hi all,
We are pleased to announce the release of v4.21 of SonarLint 
for Visual Studio 2015, 2017, and 2019.
This release significantly improves the performance of C/C++ analysis, and also adds the ability create a “reproducer” help the developers at SonarSource diagnose issues with C/C++ analysis.
The steps for creating a reproducer are documented in the wiki.
