❔ Just trying to use Accord.Video.FFMPEG in C# project

Sorry if my question is super stupid, literally 1 day old in C# (I have prog. exp. in other langs though) I'm getting the The type or namespace name 'FFMPEG' does not exist in the namespace 'Accord.Video' (are you missing an assembly reference?) triggered by line 19 in the code. When I searched for this error I thought maybe I should follow the steps https://stackoverflow.com/questions/4764978/the-type-or-namespace-name-could-not-be-found.
But I'm not even sure... - how to check Accord.Video.FFMPEG's DDL version? - Accord.Video.FFMPEG DDL's version is 3.8.0? No, right? - Is Accord.Video.FFMPEG's even a DDL ? It seems like I just need to match .NET and DDL versions? To do that maybe I can follow this https://stackoverflow.com/questions/10877913/how-do-i-change-the-net-framework-from-version-3-5-to-version-4-0 But ... - That's for Visual Studio, I'm on VSCode and when I right click those options dont exist - It seems like I'm using .NET6.0 which is distinct from .NET Framework whose latest version is 4.8, right? *Please see attached pictures And request additional info if needed for answering question *There are 5 distinct questions (bullet points) here, please address each if possible Thanks
