So you're almost finished with your work for the day, and feel all happy about making a final deploy, but instead of success you get this:

"Error occurred in deployment step 'Recycle IIS Application Pool': Provider load failure "

I have resolved this executing the following comands in Powershell

restart-service sptimerv4
restart-service spusercodev4
restart-service spadminv4
restart-service TrustedInstaller
restart-service Winmgmt -force

iisreset /noforce
