IAsyncDelegateCommand

IAsyncDelegateCommand

This interface abstracts the asynchronous ICommand approach and provides access to two additional methods:

Methods

• ExecuteAsync : the async (Task based) version of ICommand.Execute.
• RaiseCanExecuteChanged : inherited from the base interface [IDelegateCommand](IDelegateCommand) which provides access to the CanExecuteChanged` event.
