When I was first playing around with Objective-C and iPhone Development, I found the website http://iphoneexamples.com a great resource on completing some simple and some more complex scenarios with the iPhone SDK. Since Monotouch has been released and benefits from the .Net framework and C#, I thought I'd put together a website which is essentially a port of that website in the hope that others starting Monotouch development would find it useful.
You can find the site over here: http://monotouchexamples.com
