Simple Example of using an ActionBar

I have been searching the web trying to find a simple implementation of an ActionBar. I have an activity that I need to show a menu on and I've overridden:

public override bool OnCreateOptionsMenu(Android.Views.IMenu menu)
    {
        this.MenuInflater.Inflate(Resource.Menu.main_menu, menu);
        return true;
    }

Here is my main_menu.xml:

<?xml version="1.0" encoding="utf-8"?>
< menu xmlns:android="http://schemas.android.com/apk/res/android">
  < item android:id="@+id/mnuEditTeam"
        android:title="Edit Team" />
< /menu>

I'm using Holo.Light theme since I can't seem to figure out how to get the Light theme to work with ActionBar (I get a null reference exception when trying to access it).

Is there a simple sample out there that shows how I can accomplish this? I don't want to use tabs, just a simple menu.
