class Solution { static void Main(String[] args) { // Declare a variable named 'inputString' to hold our input. String inputString;

    // Read a full line of input from stdin (cin) and save it to our variable, input_string.
    inputString = Console.ReadLine(); 

    // Print a string literal saying "Hello, World." to stdout using cout.
    Console.WriteLine("Hello, World");
    Console.WriteLine("{0}", inputString);
    Console.ReadLine();

    // TODO: Write a line of code here that prints the contents of input_string to stdout.
}

}

In c# this code is working fine in VisualStudio 2017. Why is not passing the test? Please can anyone help?
