I kept getting an error in Github actions, the error was "could not find public class name" even though the Main class is capitalized. I don't know what I'm doing wrong here

When using dotnetfiddle as instructed by my teacher, the error message I received was "Public Main() method is required in a public class" but like I mentioned above, making sure the Main function was capitalized did nothing

CodePudding user response：

The error message you're receiving is because your Main method is not declared as public. In order for your program to run, the Main method must be declared as public.

To fix this, simply change the declaration of your Main method from:

static void Main()

to:

public static void Main()

CodePudding user response：

could not find the public class name

is Java error, you can refer to

and if you really want to target lower .net versions then you can simply change the main method to public static void Main()
