I don't know of any .net libraries specifically, but there's a number of implementations available on GitHub that you could take a look at - here's another PHP one, for example: https://github.com/etsy/applepay-php
Payment decryption is fairly straightforward if you're familiar with crypto, and is achievable using something like OpenSSL. There's some documentation on the exact process here:
