Description John Miller [MSFT] 2017-10-24 18:43:26 UTC
## Overview

The native CGAffineTransform[1] uses properties a,b,c,d,tx,ty while the Xamarin.iOS CGAffineTransform[2] uses xx,xy,yx,yy,x0,y0 names. 

It's preferable that the names of the Xamarin.iOS CGAffineTransform match the native types so that documentation is easier to understand when working with Xamarin.iOS.

Update:

Wrong link for [2]. It should be:

Comment 2 Rolf Bjarne Kvinge [MSFT] 2017-10-25 08:40:02 UTC
We can't change existing names (to maintain backwards compatibility), but we might consider adding additional properties that just calls the existing ones.

I wonder if this is something we can do with extensions once (if?) C# has support for "extension everywhere" (https://github.com/dotnet/csharplang/issues/192)
