I am trying to build a simple C# console application but it will not
compile.  VS doesn't recognize the "console" keyword. Here is the code:

using System;

namespace con_hello
{
    /// <summary>
    /// Summary description for Class1.
    /// </summary>
    class Class1
    {
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        static void Main(string[] args)
        {
            //
            // TODO: Add code to start application here
            //
            console.writeline("hello");
        }
    }
}

and the error message generated is:

The type or namespace name 'console' could not be found (are you
missing a using directive or an assembly reference?)

What gives?
