Must be implemented, must not throw a MethodNotImplementedException.
A dark frame or bias exposure may be shorter than the V2 ExposureMin value and for a bias frame can be zero. Check the value of and allow exposures down to 0 seconds if is false. If the hardware will not support an exposure duration of zero then, for dark and bias frames, set it to the minimum that is possible.
Some applications will set an exposure time of zero for bias frames so it's important that the driver allows this.
