Windows 10: TPM Virtual Smart Card creation

Hello,


I'm having an issue regarding TPM Virtual Smart Card creation. I'm using a method from Windows.Devices.SmartCards.dll, SmartCardProvisioning class, RequestVirtualSmartCardCreationAsync(String, IBuffer, SmartCardPinPolicy), and I'm continuously getting an error showing:

Element not found. (Exception from HResult:0x80070490)


Stack exception is shown below:


at Windows.Devices.SmartCards.SmartCardProvisioning.RequestVirtualSmartCardCreationAsync(String friendlyName, IBuffer administrativeKey, SmartCardPinPolicy pinPolicy, Guid cardId)

at POC_VSC.TPMVSC.<ScenarioCreateTpmVirtualSmartCard>d__3.MoveNext() in D:\Projects\POC_VSC\POC_VSC\TPMVSC.cs:line 87


A line below is responsible for the error:


SmartCardProvisioning cardProvisioning = await SmartCardProvisioning.RequestVirtualSmartCardCreationAsync(
"Contoso Virtual Smart Card", adminKey, pinPolicy, Guid.NewGuid());

Complete method I'm using is:

public async void ScenarioCreateTpmVirtualSmartCard()
{
IBuffer adminKey = CryptographicBuffer.CreateFromByteArray(
new byte[] {
0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08,
0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08,
0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08
});
SmartCardPinPolicy pinPolicy = new SmartCardPinPolicy()
{
MinLength = 8,
MaxLength = 127,
LowercaseLetters = SmartCardPinCharacterPolicyOption.Allow,
UppercaseLetters = SmartCardPinCharacterPolicyOption.Allow,
Digits = SmartCardPinCharacterPolicyOption.Allow,
SpecialCharacters = SmartCardPinCharacterPolicyOption.Allow
};
SmartCardProvisioning cardProvisioning = await SmartCardProvisioning.RequestVirtualSmartCardCreationAsync(
"Contoso Virtual Smart Card", adminKey, pinPolicy, Guid.NewGuid());
if (cardProvisioning == null)
return;
}

I'm using VS 2017 and I'm running this example on Windows 10. Any help or suggestion would be really appreciated...

Error in creating tpm virtual smart card on Windows 10

When I try to create a tpm virtual smart card under in command line with adminstrator privilege,

it returns the error: the card cannot be accessed because the maximum number of PIN entry attempts has been reached. (The error code is 0x8010006c.)

The command I use is : tpmvscmgr.exe create /name tpmvsc /pin default /adminkey random /generate.

Anybody knows what's wrong with it?
