@BHoMBot check project-compliance

[bhombot-ci]

@FraserGreenroyd to confirm, the following actions are now queued:

• check project-compliance

[bhombot-ci]

@FraserGreenroyd 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:
