error cs0234

This is my code:

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

}

} This is the error:

Program.cs(6,16): error CS0234: The type or namespace name console' does not exist in the namesp aceSystem'. Are you missing an assembly reference?

Can you plz tell me what is the problem?

Did you write this: using System; at the beginning of the code?

:point_right: It looks like you misspelled "Console" by writing it "console" (lower case "c").

Remember, C# is case-sensitive.

probably was because you didn't save the changes after you changed it to an upper case 'C'

I'm getting the same error message. I've been trying to figure out the problem and have tried re-writing it several times. Still the same problem.
