C# Wrapper for Telegram API - Not BOT API

Please only bid if you either have experience with the Telgram API (not the Bot API) [login to view URL] or you have reviewed the documentation thoroughly. This is not your typical API. This project is to build a C# .NET wrapper for the Telegram API. In addition to the API wrapper, a simple test console application that utilizes the API must be provided as a demo for the API. The API wrapper must support all functions required for the following features: 1) Authentication 2) Joining a Group or Channel 3) Sending and Retrieving Chat, Group, and Channel Messages 4) Downloading files from a Chat, Group, and Channel 5) Retrieving Chat, Group, and Channel Metadata 6) Getting Profile information for a user 7) Retrieving available channels 8) Searching channels based on a search term 9) Searching User’s current messages based on a search term Note that only 18 layers are shown in the Telegram API online documentation because it has not been updated recently, and many of the functions needed are not in those layers. Functions from other layers must be implemented using the official Telegram API sample code as a guide. The console app must behave as follows: 1) User enters phone number 2) User enters code sent to phone by Telegram 3) App displays every chat, channel, group, etc. the user is currently a participant in 4) User can select a chat, channel, or group and see the messages from that source 5) User can send a message in a chat or group 6) User can search for available Channels 7) User can join a channel 8) The app’s connection must persist through restart. The user shouldn’t have to re-enter a phone number and verification code if the app restarts or is open for a long period of time. The test app does not have to support any functions outside of the scope of what is listed above. The test app should have a simple configuration that contains all the Telegram app configuration values. (For example: api_id, api_hash, etc.) that would be required to interact with the API. The API Wrapper and test app must follow all Security Guidelines outlined by Telegram.
