var mintReceipt = await client.MintNftsAsync(new MintNftParams
{
    Token = createReceipt.Token,
    Metadata = new[]
    {
        (ReadOnlyMemory<byte>)Encoding.UTF8.GetBytes("{\"name\":\"NFT #1\"}"),
        (ReadOnlyMemory<byte>)Encoding.UTF8.GetBytes("{\"name\":\"NFT #2\"}"),
        (ReadOnlyMemory<byte>)Encoding.UTF8.GetBytes("{\"name\":\"NFT #3\"}")
    }
});
Console.WriteLine($"Minted serial numbers: {string.Join(", ", mintReceipt.SerialNumbers)}");
