How to obtain xpub string representation from ExtPubKey

[driquelme]

Newbie here trying to extract a xpub key from a mnemonic. I already have an instance of an ExtPubKey, but I haven't been able to get a string representation of it, how can I do it?

Never mind, I figured I could do this:

BitcoinExtPubKey seedMainNetPublickKey = derivedETHPublicKey.GetWif(Network.Main);
Console.WriteLine(seedMainNetPublickKey.ToString());
