I am currently trying to deploy a timer job to my SharePoint site. for the first deployment I forgot to implement a public default constructor for the Timer Job Class. And now I am stuck because I cannot retract the old solution and update it with the newer one with the public default constructor implemented.

I have already tried it with the Manage farm solutions page and got an error like this:

enter image description here

I have also tried this one here:

Uninstall-SPSolution -Identity testproject.wsp -allwebapplications
Remove-SPSolution -Identity testproject.wsp -force

With the same error and I am driving crazy right know because I don't know any more solutions to handle this error.

Can anyone tell me how I can "kill" the corrupted solution from my farm so that I can deploy the correct one?

EDIT: I have also tried the "Update-SPSolution" but get the same error...

  • Have you tried Update-SPSolution ?

Please try to copy your DLL to GAC directly. You can do this manually or use some VS plugins like CKSDev or Fishbone

  • Yes, this made it! I have done it with CKSDev and Mavention. Thanks
