hi @epvanhouten and welcome to our community forum!
First of all:
- what version of SonarQube are you using? or are you using SonarCloud?
- what version of Scanner for MSBuild are you using - the .NET framework or the .NET Core one?
Also
- could you share the debug logs of the End step (run the begin step with
/d:sonar.verbose=truein order to enable verbose logging - see docs)?
To be able to analyze the perf issue, we will need access to the UCFG files. These are in the .sonarqube\out\ucfg_cs2 folder. If you want, you can zip that folder and send it in a private conversation on the forum. We will be able to run the analysis locally using those files and eventually find the performance hotspots.
Please note that the UCFG files are an abstraction of the source code (the Control Flow Graph), so it is sensitive information: names of namespaces, classes and methods (hence they should be sent via a private message on the forum)
