+- To run with code analysis, instead use `powershell ./build.ps1` or `build.sh`. This is currently only supported under windows due to [resharper cli shortcomings](https://youtrack.jetbrains.com/issue/RSRP-410004). Alternative, you can install resharper or use rider to get inline support in your IDE of choice.
