Thank you for reaching out to Microsoft Q & A forum.
It looks like the Try .NET editor is already including some hidden code, which is why you're seeing errors when adding the "using System;" statement and the "public class Program" declaration. Try using only the following portion of the code in the editor:
Console.WriteLine(
This is because the Try .NET environment already handles the necessary setup behind the scenes. Here's a step-by-step guide:
Clear the editor: Remove any existing code in the Try .NET editor.
Enter the simplified code: Use only the Console.WriteLine("Hello world!"); line.
Run the code: Click the green Run button.
This should resolve the errors you're encountering. If the issue persists, try refreshing your browser or using a different browser to see if that resolves the problem.
