c# - How to get the primary key of an object after it is saved with DbContext -

given out of context snippet of code:

var calibration = new calibration {     calibrationtype = selectedtest.testtypeid     ,expiration = expirationdate     ,lastsaved = datetime.now     ,statustypeid = 1     ,technicianid = selectedtechnician.id     ,phases = buildcalibrationphases() };  db.calibrations.add(calibration); db.savechanges(); 

is there way entity framework primary key chosen(seeded) calibration object after db.savechanges(); completes?

in other words how can primary key object after committed?

reload entry in context:

db.entry(calibration).reload(); 

then can access newly created pk
