await client.LoginUserIfNeeded();

client.RegisterUpdateType<UpdateNewChannelMessage>((channelMessage, updatesBase) =>
{
    Console.WriteLine("Message In : " + channelMessage.message.Date.ToString("F"));
});

Or Listen For New Message From Channel <b>AND</b> Deleted Messages :

{
    Console.WriteLine("type of new update is" + p.GetType());
});

You Can Register a Specific Chat Type With Passing a Peer Type :

await client.RegisterChatTypeAsync<PeerChannel>((update, channel) =>
{
    Console.WriteLine($"RegisterChatTypeAsync:PeerChannel: {channel.channel_id} with type : {update.GetType()}");
    return Task.CompletedTask;
});

Also You Can Search For A Specific ID Inside Of Upcoming Updates(Including Update Type) :

client.RegisterUpdateWithId<UpdateUserTyping>(121212, (update, upBase) =>
{
    Console.WriteLine($"user is typing : {update.user_id}");
});

Blocking

currently all of the mentioned methods will NOT block the current thread, so they has to be called at the startup of your application and then the flow of your program should be blocked somewhere else.

using the *Block overloads of these methods you can block your current thread:

// this is NOT going to block the current thread
client.RegisterUpdateType<UpdateNewChannelMessage>(async (messages, upBase) =>
{
    await Task.Delay(2, cancellationToken);
    Console.WriteLine($"new message");
});

//this WILL block the thread so the code will not continue after this point until the cancelation token is requested
client.RegisterUpdateTypeBlocking<UpdateNewChannelMessage>(async (messages, upBase) =>
{
    await Task.Delay(2, cancellationToken);
    Console.WriteLine($"new message");
}, cancellationToken); // the token is also optional, you can skip it
