Cannot upload files, no ImageInput.FromFile()

[JulesVerny]

Some of this code does not compile. For example ImageInput.FromFile( ) is not in any of the standard C# or anywhere in this package.

How are we supposed to upload Image files from our local drives, if this code does not compile ?

TheOpenAI_api.Chat.GetResponseFromChatbotAsync( ) does not seem available either.
