The problem is likely your $PATH -- Mono was installed with /usr/local/
as the installation prefix, thus there should be a /usr/local/bin/mcs
script, but /usr/local/bin isn't within PATH.

Try doing this in your shell:

        export PATH=/usr/local/bin:$PATH
        mcs --help

Running apps from the command line is ~completely different from running
ASP.NET apps.

To run an ASP.NET app, you need to do one of two things:

1. cd path/to/your/asp.net/app, then run xsp2.  This will start a local
web server listening to http://localhost:8080.

2. Configure Apache and mod_mono: http://mono-project.com/Mod_mono (and
likely lots of other Google-able sources).

Finally, for command-line apps (not ASP.NET apps), you should read over:
