Will Argon2id.ComputeHash always make use of the full buffer?

[kikaragyozov]

If a buffer is allocated with a size of Argon2Id.MaxHashSize and then passed to Argon2Id.ComputeHash as the hash parameter, can I assume that the full buffer size will be used by the underlying implementation, i.e a total of Argon2Id.MaxHashSize bytes will be written down?

Good question. The actual output string may be shorter than that, but it will be padded with null characters, so you can treat it as that size.
