An application uses Microsoft Point of Service (POS) for .NET 1.12 to claim a device. In this case, applications that are running under a different user account cannot claim this device. When this problem occurs, POS for .NET 1.12 performs incorrect claim logic and incorrectly returns an ArgumentNullException exception. Additionally, successive attempts by the other user account to claim the device fail even after the device is released.
Notes
Notes
- This problem does not occur if applications that claim the device are running under the same user account.
- The ArgumentNullException exception is not the exception that corresponds to the failure that occurs. When this problem occurs, you expect the exception that corresponds to the failure to be returned.
