Introduction

The SonarScanner for .NET makes it easy to manage your SonarQube Cloud analysis of your .NET projects without a need for any additional tools or resources.

Even if you’re already familiar with SonarQube Server and SonarQube Cloud, analyzing a .NET application is a little different than when analyzing other languages. Whereas the SonarScanner normally scans existing code or already built projects, the SonarScanner for .NET analyzes the code while the build is in process. The SonarScanner for .NET makes it easy to manage the analysis of your .NET projects including projects containing file types for select languages using a Multi-language analysis parameter, without needing any additional tool or resource.

The SonarScanner for .NET is the recommended way to launch an analysis for projects using the msbuild or dotnet build tools. It is the result of a collaboration between Sonar and Microsoft.

The SonarScanner for .NET is distributed as a .NET Core Global Tool, in the Azure DevOps Extension, and in the Jenkins Extension.

It supports .NET Core on every platform (Windows, macOS, Linux).

Analysis process with the SonarScanner for .NET

To run an analysis using the SonarScanner for .NET, you first need to make your code analysis work and set up your PR decoration. The final step is to integrate the coverage import.

1. Install the prerequisites in your environment (Java). See the Installing the scanner page.

2. Download the correct SonarScanner version for your .NET runtime, and install it on your CI.

3. Then work on your pipeline. These details are on the Using the scanner page;

   • specify your Begin step arguments to prepare your project for analysis,

   • Build your project which will generate the analysis data,

   • and define the End step arguments to collect the analysis data.

4. Finally, focus your analysis as part of your build process by setting up your .NET test coverage using a third-party tool to access important metrics.
