How to program on Visual Studio 2019

Question

I'm approaching the end of my C# course with Codecademy and want to slowly get comfortable using Visual Studio 2019.
So far the codecademy platform provides me with all the comforts but I don't understand yet how to build a complete program with class files, interface files etc. and be able to make them work together.

I'd like to find a good resource for learning just that: how to program on Visual Studio and make a program work with all of its complexity.

Any suggestions for good and well organized tutorials or courses for this topic specifically?

Thanks a lot!

Answer 1

First you have to get the IDE from official Microsoft website. And then download some extensions for c#

Answer 2

That has all been done and I've been playing with it a bit. But I still don't know how to use the interface to build class files, interface files and make them run as one program. I'm searching for some tutorials/course that will help me learn that step by step.
