Cause

csc.exe does not have permissions to the C:\temp folder or other mapped folder in the TEMP system variable.

Resolution

Give the IIS_IUSRS local computer group on the SMP permissions to the C:\Temp directory.
You need to edit the special permission on the C:\Temp folder for that.
See attached screenshot as example.
You can also add the delete subfolders and files special permission to the IIS_IUSRS group to make sure no junk is left behind.
