How do I add this to my project?

Library isn't ready for production usage, that's why no Nu-Get package available.

To use it follow next steps:

1. Clone Telegram.Net from GitHub
2. Compile source with VS2015
3. Add reference to Telegram.Net.Core.dll to your project.

Starter Guide

Quick Configuration

Telegram API isn't that easy to start. You need to do some configuration first.

1. Create a developer account in Telegram.
2. Goto API development tools and copy API_ID and API_HASH from your account. You'll need it later.

Initializing client

To initialize client you need to implement your own instance of ISessionStore which Telegram.Net will use to save Session info.

class MySesionStore: ISessionStore
{
	//...
}

Next, create client instance and pass all required parameters. You need your API_ID and API_HASH for this step.

var client = new TelegramClient(sessionStore, apiId, apiHash);

If you are going to handle Update notifications from Telegram server or network connection state, then you should subscribe to appropriate events.

client.UpdateMessage += UpdateHandler;
client.ConnectionStateChanged += ConnectionHandler;

And finally you need to call Start method. It returns bool indicating if client has successfully connected to the server. If not, library will automatically try to reconnect every 8 seconds.

Now you can call methods.

All methods except IsPhoneRegistered requires an authenticated user. Example usage of all methods you can find in [Tests].

FAQ

I get an exception: "Channel was closed"

This can happen when sending your request was successfull but before receiving the response network connection was lost. This should be considered as missing internet connection situation.

Why I get FLOOD_WAIT error?

It's Telegram restrictions. See this
