How do you delete a SharePoint 2010 TimerJob?

Question

I have created a custom TimerJob in Visual Studio 2010 using an Empty SharePoint project. I added some functional code and deployed it to my SharePoint site. The TimerJob ran according to plan.

I then made a change to my project's code and redeployed the solution. I got the following exception:

Error occurred in deployment step 'Add Solution': An object of the type <JobName> named "<JobName>" already exists under the parent Microsoft.SharePoint.Administration.SPWebApplication named "<App Name>".  Rename your object or delete the existing object.

I opened up SharePoint 2010 Management Shell and ran the following code to delete the TimerJob:

//To get the TimerJobs id
Get-SPTimerJob | where { $_.name -like “<JobName>” } |ft id,name
//With the id I got the job
$job = Get-SPTimerJob id
//I deleted the job
$job.Delete()

I then checked to see if the job had been removed from the site at CentralAdministration > Job Definitions and it was not longer visible in the list.

I redeployed my Visual Studio solution and got the same exception. Does anyone have any idea why the TimerJob was not deleted and/or why I am getting this exception?

Your solution (WSP) needs to be removed as well as deleting the job.

Use the Remove-SPSolution cmdlet in PowerShell, and then the Uninstall-SPSolution cmdlet.

You could add an event when the solution is removed the job is deleted too.
