Can't get System.Console.Write to print anything

Hi there, I am very new to all of this. I am at the beginning of c# basics and he is explaining the code that looks like this

class Program
{
    static void Main()
    {
      // Prompt the user for minutes exercised
      System.Console.Write("Enter how many minutes you exercised: ");

      // Add minutes exercised to total
      // Display total minutes exercised to the screen
      // Repeat until the user quits

    }
}

he then says to type into the console mcs Program.cs, ls, mono Program.exe

the program runs for him and returns the message he made but when I do it in work spaces no message comes back. Can anyone help me please?

Did you save your changes before you compiled? If not, you just created an executable from the blank program that the workspace started with.

Look for a red dot to the right of the program name in the workspace tab. That's a reminder that your changes have not been saved. You can select "save" from the "edit" menu, or just type control-s. You can see where the instructor saves his code in the video and makes the red dot vanish, but he doesn't mention that he is doing it.

I wrote mine exactly like his, but it keeps giving me the error that "the name 'system' does not exist in the current context." Which it clearly does.... sooo is there a bug?
