In Sharepoint Foundation 2013 i have developped an spsolution scoped web with an eventreceiver. It's attached to a specific list in featureactivated. When i do

update-spsolution -identity xxx.wsp -literalpath xxx -GACDeployment

It's correctly deployed but change like adding simple log are not visible. It seems keeping old version. I looked in GAC the dll version and it's the correct one.

I tryied to remove and reinstall without success


i deleted dll in temp folder too

I'm really disapointed because i have no more idea to find a solution.

We had this issue in recent past, for us this dll stuck in timer service cache. I would do the following things:

  • Restart the SharePoint timer and Admin service on all server in the farm
  • Reset IIS on all servers
