### Send a message to someone by @username
```csharp
var resolved = await client.Contacts_ResolveUsername("username"); // without the @
await client.SendMessageAsync(resolved, "Hello!");
var resolved = await client.Contacts_ResolveUsername("MyEch0_Bot"); // username without the @
await client.SendMessageAsync(resolved, "/start");
```
*Note: This also works if the @username points to a channel/group, but you must already have joined that channel before posting there.
If the username is invalid/unused, the API call raises an exception.*

## _Telegram Client API library written 100% in C# and .NET Standard_
This ReadMe is a **quick but important tutorial** to learn the fundamentals about this library. Please read it all.
This ReadMe is a **quick but important tutorial** to learn the fundamentals about this library. Please read it all.
This library allows you to connect to Telegram and control a user programmatically (or a bot, but [Telegram.Bot](https://github.com/TelegramBots/Telegram.Bot) is much easier for that).
All the Telegram Client APIs are supported so you can do everything the user could do with a full Telegram GUI client.
>⚠️ This library relies on asynchronous C# programming (`async/await`) so make sure you are familiar with this advanced topic before proceeding.
>If you are a beginner in C#, starting a project based on this library might not be a great idea.
