My VS build consistently halted mid process but couldn't be stopped w/o force stopping the process. I attempted all the solutions proposed here, but wasn't successful.
After a while I attempted to go to the code folder and delete the bin / obj folders and I found that there was a process that was holding certain files w/i bin / obj folder content hostage. I wasn't able to resolve this so I simply restarted the computer then once restarted I deleted the bin / obj files and then performed a rebuild w/i VS. This completed the rebuild and I was able to build from then on.
