method "GetLogBiasFieldAsImage" missing in N4BiasFieldCorrection c# implementation

Thank you so much for answering!
I am using simpleITK version 2.0.2 (maybe 2.0.2.0) downloaded from this place (downloaded the zip at the bottom line of this screen capture):

I expected it to have the method GetLogBiasFieldAsImag() because it was listed here:

I realize now that it is not the same version (oops).
What can be done about it? Should I download a newer sitk version? (if yes, which and where from?)
Of course its not that I must use this specific method. Any method that would give me the full-resolution corrected image, through the full-resolution Bias Field or directly, would work for me.
Only it must be available in the C# implementation.
Thanks again!
