Mikolaj needed to customize Frame corner radius to have just the top or bottom corners rounded, whereas the rest corners should stay rectangular.

In this post, he shows how to create a renderer to help control the corners.

NUGET OF THE WEEK

sthewissen/Xamarin.Forms.DebugRainbows

The package you didn't even know you needed! Have you ever had a piece of XAML code that didn't produce the layout you expected? Did you change background colors on certain elements to get an idea of where they are positioned? Admit it, you have and pretty much all of us have at some point. Either way, this is the package for you! It adds a very colorful debug mode to each of your ContentPages that lets you immediately see where all of your elements are located!
