@mwilliamson @Thoorium any updates on this?

The sample is outdated. There is no generic `BotBase` currently in the library, only non-generic `BotBase`, I think you should use that. https://github.com/TelegramBots/Telegram.Bot.Framework/blob/0d0242904941e4ab9ef5348490060e04f5e67aa8/src/Telegram.Bot.Framework/BotBase.cs
