Hello Visual Studio users,
I am excited to announce this new version of SonarLint :sonarlint: for Visual Studio, that is loaded with great new features for both C, C++ and .NET developers!
If you are a C or C++ developer using Visual Studio to develop cross-platform applications, or if your projects use open-source libraries, or if for any other reason you prefer CMake to the native Visual Studio projects for C++, then you will appreciate that we are launching the support for CMake projects 
In order to benefit from it you need to update your SonarLint to the latest version, and also ensure that:
- you are using Visual Studio 2017 or 2019
- you are using MSVC to compile your project
- you configured CMake to export the compilation commands; in facts those commands are needed by our analyzers to correctly report issues in your code. To do that, you just need to ensure that the variable CMAKE_EXPORT_COMPILE_COMMANDS is set to ON (you can refer to: CMAKE_EXPORT_COMPILE_COMMANDS — CMake 4.0.0 Documentation).
And even if you don’t use CMake, this new SonarLint version will greatly improve the detection of issues in your code:
- We improved the symbolic execution engine to drastically reduce issues found in infeasible execution paths
- We added 4 new bugs and code smells rules for C++ 20
If you are a C# developer, you will benefit of many new rules covering several C# 9 features:
- native sized integers
- module initializers
- partial methods
- target typed conditional expressions
- Lambda discard parameters
- Attributes on local functions
- Static lambdas
- Function pointers.
You can read more in our release notes if you wish. Once you get a chance to try the latest version, don’t hesitate to leave us your feedback.
