This is a mix of code that was developed during our effort to port eM Client to macOS. It is a hodgepodge of various projects and experiments. The notable ones are listed below. The code is released as-is.

To test the experiments:

• Open MacPlayground.sln in Visual Studio for Mac
• Set default project to FormsTest.app
• Run

The System.Drawing directory contains a fork of the https://github.com/mono/sysdrawing-coregraphics project. We have enhanced the API surface to be compatible enough with System.Drawing to run System.Windows.Forms on top of it. In addition we have implemented some missing APIs and fixed compatibility issues with pixel rounding.

The System.Windows.Forms directory contains a fork of the Mono System.Windows.Forms implementation. It contains a Cocoa backend to allow applications run on 64-bit macOS systems. Layout code was heavily overhauled and debugged on both a test application and a full UI of eM Client. Further experiments were made with replacing some controls with their native counterparts (akin to https://github.com/Clancey/MonoMac.Windows.Form), which can be done on per-control basis.
