I created a TimerJob which is activated upon Feature activation. Because I didn't know better, I forgot to add an public default constructor and now I always get this exception: "Error occurred in deployment step 'Retract Solution': Lists.JobTimerReminder cannot be deserialized because it does not have a public default constructor." when I want to retract the solution (or try to disable the Feature, or even when I run 'Get-SPTimerJob' in the Management Shell). I cannot work on and redeploy my project (via Visual Studio) because it has to be retracted beforehand.
How can I get rid of this thing?
