C# Basics Challenge "Hello!"

I cannot figure out why the program will not run. I believe I followed the instructions correctly, but I still get an error. Please help.

Program.cs 
class Program
{
    static void Main(string[] args)
    {
        System.Console.WriteLine("Hello!");
    }
}

Your code looks OK to me. So I tried it in the challenge and the error message doesn't seem to be about your code but about the test system itself.

You might need to pass this one over to the Support folks.

I am also having the same issue. I'm sure my code is correct. The error I get is:

Bummer: System.IO.IOException: Read-only file system at System.IO.FileSystem.CreateDirectory(String fullPath) at System.IO.Directory.CreateDirectory(String path) at Microsoft.Extensions.EnvironmentAbstractions.DirectoryWrapper.CreateDirectory(String path) at Microsoft.DotNet.Configurer.FileSentinel.Create() at Microsoft.DotNet.Configurer.DotnetFirstTimeUseConfigurer.Configure() at Microsoft.DotNet.Cli.Program.ConfigureDotNetForFirstTimeUse(INuGetCacheSentinel nugetCacheSentinel, IFirstTimeUseNoticeSentinel firstTimeUseNoticeSentinel, IAspNetCertificateSentinel aspNetCertificateSentinel, IFileSentinel toolPathSentinel, Boolean isDotnetBeingInvokedFromNativeInstaller, DotnetFirstRunConfiguration dotnetFirstRunConfiguration, IEnvironmentProvider environmentProvider) at Microsoft.DotNet.Cli.Program.ProcessArgs(String[] args, ITelemetry telemetryClient) at Microsoft.DotNet.Cli.Program.Main(String[] args)

That's the same error I saw when testing Sherowin's code. The "Read-only file system" doesn't sound like anything you can control, and is likely a configuration issue in the server. Only the staff can fix that so I suggested contacting Support directly.
