c# - Order of event handler execution

Question

If I set up multiple event handlers, like so:

_webservice.RetrieveDataCompleted += ProcessData1;
_webservice.RetrieveDataCompleted += ProcessData2;

what order are the handlers run when the event RetrieveDataCompleted is fired? Are they run in the same thread and sequentially in the order that are registered?

Answer 1

Currently, they are executed in the order they are registered. However, this is an implementation detail, and I would not rely on this behavior staying the same in future versions, since it is not required by specifications.
