"args" in Main(string[] args) is null

[ViIvanov]

Describe the bug

I have opened try.dot.net web site and ran next code:

internal static class App
{
  private static void Main(string[] args) => System.Diagnostics.Debug.Assert(args != null, $"{nameof(args)} != null");
}

Did this error occur while using dotnet try or online?

• [ ] dotnet-try
• [x] online

What kind of error was it?

• [ ] User Interface (UI): For example the output never displayed
• [ ] Service Error: For example "The service is temporarily unavailable. We are working on it"
• [x] Other: "Run" command prints Fail: args != null, so args parameter of the Main method is null.
