I needed to implement a zoom level similar to Google Maps style for MonoTouch iOS and lucky me after doing little search on the web I found this article http://troybrant.net/blog/2010/01/set-the-zoom-level-of-an-mkmapview/ written byTroy. This is exactly what I was looking for except it was in Objective-C.
So with my little knowledge of Objective-C I copied his code and converted this to C# for using MonoTouch library. I hope this code snippet will help other monoTouch coders as well. Also a big thanks to Troy for such a nice article.
