Hello,
I just installed Visual Studio 2019 onto my laptop and I can't run or debug anything since I installed the program. I am assuming I have nothing in my "solutions". Is that why nothing is working? I appreciate if someone can guide me to fixing this error.
A core feature of Visual Studio that allows developers to inspect, analyze, and troubleshoot code during execution.
A high-level, general-purpose programming language, created as an extension of the C programming language, that has object-oriented, generic, and functional features in addition to facilities for low-level memory manipulation.

You seem to be missing a function named main.
The code that you are showing, as well as the name of
the program, indicates that you are trying to build a
C# (C Sharp) program. You have posted your question with
the C++ "Tag". You should remove that Tag and add the
dotnet-csharp Tag instead.
Thanks I didn't realize that. I changed it .

Hi, a simple solution for me was using the default folder they specified to keep the programs in. For example
C:\Users\<Your Name>\source\repos
This was the one they automatically set for you and if you change where you store the project, it may not know where to look for the files.
Hope this helps!

Hi HieuHO,
In visual studio , you need a solution with a project for C# development(build, debug..., etc). You can follow this document to start the trip of C#: Quickstart: Use Visual Studio to create your first C# console app

This did now work for me :(. I am still missing a solution when I create it from the way the instruction were told. any other Suggestion?
Hi @Hieu HO , it seems that there is something wrong with visual studio installation. You can try to re-install visual studio. If it doesn't work, I'm afraid that you need to re-install your system.
Before writing the program, try creating a project: go to menu, File, New, Project, select C# language, select “Console App (.NET Framework”), press "Next", etc. This will create a simple program that can be run. Then enter your code inside the Main function.
