• Remove the "using" line and try compiling (F5).
• Add the System prefix. to the Console.
  You can write it manually or use a hint (expand the bulb symbol):
  
• The clue indicates 4 solutions. Let's choose the latter - the System.
prefix
• As you can see the error has disappeared, but the next reference to classes in the System namespace will require us to enter the System prefix. Therefore it is more convenient to specify it once with "using" at the begining of the file.

 foreach (string arg in args)
             {
             Console.WriteLine($ "Argument: {arg}");
              } 

 try
        {
            y = int.Parse(yStr);
        }
catch (FormatException fe)
        {
            Console.WriteLine("Oh no!" + Fe.Message);
        }
finally
        {
            Console.WriteLine("something else");
        } 

• user specifies the maximum size of the multiplication table
• A tag of the given size is displayed
• Use.
• for this task
  • double for loop,
  • formatted (up to 2 digits) display of numbers {number: d2},
  • printing without breaking Console.Write lines
• The effect should look something like this:
  
  
  

 namespace MultiplicationTable
{
public static class FormatField
{
public static string Field(int number, int width)
{
return number.ToString().PadLeft(width) + "|";
 }
}
