@pawelbaran fix requested for project compliance. The errors with the CSProject (`.csproj`) files have been recorded as annotations on the checks tab. I will apply the fixes to every case detailed on the checks tab with the exception of any references to the target framework. I am unable to provide fixes to the Target Framework automatically, these will need to be performed manually. If you want to perform the fixes in a different manner please resolve this manually and rerun the check. If you are happy for me to go ahead and perform this action, please reply with: > @BHoMBot fix project file ref. `24298883442`
