VB.NET Core Classes in a Nutshell

MulticastDelegate

Synopsis

This is the base class for multicast delegates. Multicast delegates are identical to normal delegates, except that their invocation list can hold more than one method at a time. You can use Delegate.Combine() to add a method to the list and Delegate.Remove() to remove one. When you invoke a multicast delegate, the methods are invoked synchronously one after the other. An error in one method can prevent the delegate from calling the other methods in its list.

Multicast delegates can also be invoked asynchronously, meaning that the entire call chain is invoked serially by a single thread out of the system thread pool. If it is desirable to invoke each delegate in the chain on its own asynchronous thread instead, then use GetInvocationList() to obtain the list of delegates and asynchronously invoke each one.
