I started a course about C#, but when I tried to run the code there was no button, just a button named attach.

I searched online and have found no clue on how to solve this problem.

The Button

I was expecting to run my code in the Visual Studio Community.

    You're editing a standalone file. You need to create a Project first. – Dai Aug 21 '23 at 23:50

You can execute the code using the C# interactive window if you just want to execute C# code with no project.

  1. Highlight the code you want to run
  2. Right click and select- "Execute in C# Interactive"

To get the buttons you are asking about then you need to add your .CS file to a project. The easiest solution is to create a new project with the option to use existing files. Microsoft link : Create a project from existing code files Project from Existing Code

You are using top-level statements. See link with explanation of this style vs a "Program.Main" type style program. A lot of examples will use the Program.Main style C# console app template generates top-level statements

If you receive an error like :

Error CS8370 Feature 'top-level statements' is not available in C# 7.3. Please use language version 9.0 or greater.

  1. Right click and select quick actions
  2. Select Convert to Program.Main style

Convert to Program.Main style
