Having issues setting up Avalonia

Im trying to make a game engine with C# (as a hobby) so to start and since I'm using Linux with VSCode, I chose Avalonia. After installing the packages, the function StartWithClassDesktopLifeTimes is not working because 'AppBuilder' does not contain a definition for 'StartWithClassDesktopLifeTimes' and no accessible. I don't what I did wrong or what extension I am missing.
