GitHub Language Bar Not Showing On Newly Uploaded C# Project Repository

Good day!

I published a C# Console project to my GitHub repository few days ago and when checking back on the repository, I noticed that the programming language bar or indicator is missing. Only the updated status is shown as seen from the screenshot below.

I did some research and have'nt found a specific answer to my problem. What I did was I opened up my project and noticed that the access modifier of the Program class is internal.

internal class Program
{
    static void Main(string[] args)
    {        
        Console.ReadLine();
    }
}

So, I tried changing the internal access modifier of the class to public and re-published it again. Voila! The language bar or indicator is now visible.

public class Program
{
    public static void Main(string[] args)
    {
        Console.ReadLine();
    }
}

Cheers!
