Question

I experienced the same issue with a slightly different stack trace:

Error MSB4018: The "SqlBuildTask" task failed unexpectedly. System.IO.IOException: The file exists.

Turns out this is a issue with the Temp directory for the service account I was using, I think if you exceed X number of folders/files in that directory the publish will no longer work. Fixed this issue by following the instructions mentioned here (for my service account):

• Go start-> run
• Type %temp% and click ok
• Make sure you are in the folder /Local/Temp
• Delete everything in this folder
