What you've described sounds, at least approximately, like you've done things right. In order to help, I just created a fresh new centos7 VM, installed from the centos7 minimal DVD. Here are my exact steps:

sudo yum -y groupinstall base
sudo rpm --import "http://keyserver.ubuntu.com/pks/lookup?op=get&search=0x3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF"
sudo yum-config-manager --add-repo http://download.mono-project.com/repo/centos/
sudo yum -y install mono-complete
(43 packages)

mono --version

cat > hello.cs
using System;

public class HelloWorld
    static public void Main ()
        Console.WriteLine ("Hello Mono World");

mcs hello.cs
hello.cs  hello.exe

mono hello.exe 
Hello Mono World

Works for me. What's different in your system? I tried both on the console text terminal, and ssh'd in from Terminal on OSX. Just in case there was some sort of weird terminal emulation thing messing with Console.
