While not available out of the box the idea of Hangfire is to allow you to add your own attributes and filters that will allow you to implement what you want. You can ‘inject’ such custom logic at different stages of the process.
I suggest you look at this page in particular to get you started: Using Job Filters
As to the question ‘can you get the last runtime’ the answer is a little more complex. Short answer is yes. You can get that information as follows :
Of course this only works if you have already configured you jobstorage and connection to your database where you store the hangfire data. It will return a IEnumerable<RecurringJobDto> with all your current recurring jobs including a LastExecution and NextExecution property. What you have to keep in mind though is that this information is not ‘realtime’. It might take a while for the values to be updated so using it from within the job is probably not going to be achieving the result you want.
Again (judging from your post) you probably will want to implement some custom job tracking logic of your own from within the JobFilters that does not depend on LastExecution at all.
