Can't select Debug or Release configurations in Visual Studio 2005?

When you first install Visual Studio Express, it avoids confusing beginners by hiding the build configurations. Of course, this confuses the people who understood it already...

• Select 'Tools->Options' and if it's not already checked, check 'Show all settings'.
• Now choose 'Projects and Solutions' and check 'Show advanced build configurations'.

Perhaps now that I've blogged it, I'll remember it next time... :)
