Public Member Functions
void	Dispose ()
	Releases all resources used by this instance.
void	EndTransaction ()
	Ends the current smart card transaction, releasing exclusive access while maintaining the token's state.
async Task	MaintainTransactionAsync (CancellationToken ct)
	Maintains an active smart card transaction by periodically checking the SCardStatus (in 2.5 second intervals).
void	StartTransaction ()
	Begins a smart card transaction, establishing exclusive access to the token.

Detailed Description

The CrescendoDLL.PCSC.APDUEngine class contains references to applet objects, their current properties and all the necessary internal methods to allow PCSC communication with the SmartCard.

Two construction modes determine which applets are wired:

• The Crescendo constructor (CrescendoDLL.PCSC.APDUEngine(string, CrescendoDLL.PCSC.PCSCImpl, string, byte[], bool)) and Token-based Crescendo factory register real lazy factories for every Crescendo applet — ACA, OATH, PIV, CardManager, FIDO Attestation, and FIDO Instance.
• The generic-FIDO constructor (CrescendoDLL.PCSC.APDUEngine(CrescendoDLL.Token, CrescendoDLL.PCSC.PCSCImpl)) is used for non-Crescendo authenticators. Only FIDO Instance is wired to a real applet; every other applet getter throws NotSupportedException
