Create new task at runtime

Hi guys.

Currently have an MVC5 app that will be using Hangfire to schedule some tasks.

I need to give the user the ability to create a “new” task via some UI, Unfortunately I have heard that you can create a task but you must restart the server for the task to be fired.

Can someone confirm this? Or is this not the case? If it is true is there a workaround? if its not the case then how would one create a task via UI?
