Error message “CS5001 Program does not contain a static 'Main' method suitable for an entry point”

Question

Unable to execute the following code error CS5001 Program does not contain a static \'Main\' method suitable for an entry point

What does this error message mean?

Answer 1

It means that you don't have a suitable entry point for your application at the moment.

That code will nearly work with C# 7.1, but you do need to explicitly enable C# 7.1 in your project file:

7.1

or more generally:

latest

You also need to rename MainAsync to Main. So for example:

Program.cs:

using System.Threading.Tasks;

class Program
{
    static async Task Main(string[] args)
    {
        await Task.Delay(1000);
    }
}

ConsoleApp.csproj:

  
    Exe
    netcoreapp2.0
    7.1
  

... builds and runs fine.
