SynchronizationContext is an abstraction that uses virtual methods. Using SynchronizationContext allows you don't tie your implementation to a specific framework.

WPF uses the DispatcherSynchronizationContext type that overrides Post to call Dispatcher.BeginInvoke. You can design your component that uses SynchronizationContext and doesn't tie implementation to a particular framework.
