✅ Taking user input using Console.ReadLine()

Hello guys, can someone explain why my IDE (rider) has underlined the Console.ReadLine method pls.

Console.WriteLine("What is your name?");
            string name = Console.ReadLine();
            Console.WriteLine(name);

Console.WriteLine("What is your name?");
            string name = Console.ReadLine();
            Console.WriteLine(name);

What is wrong here? what can be corrected and why pls
