These are the system requirements for developing and/or contributing to Eto.Forms. Note that these are not necessarily the same requirements for running Eto.Forms apps, which are outlined in Supported Platforms.

On Windows, you can target WPF, WinRT, Windows Forms, and GTK#2.

• Visual Studio 2019
• .NET Core SDK
• (optional) For GTK#2: GTK# for Microsoft .NET
• (optional) To bundle Eto.Mac64 apps with mono: mono for windows

Notes:

• Cannot build or run Xamarin.Mac applications
• Can build and package MonoMac applications, but cannot run them

On Mac OS X, you can target MonoMac, Xamarin.Mac, Gtk+3, or Gtk#2.

• Mono
• .NET Core SDK
• Xamarin Studio 8.6 or greater
• For App Store Mac apps: Xamarin.Mac

Notes:

• Cannot build or run WPF or WinForms applications

On Linux, you can target Gtk#2 on mono, and Gtk+3 either for .NET Core or mono.

• Mono 6.x
• .NET Core SDK
• Visual Studio Code
• For Gtk+3 (Eto.Gtk): Gtk+ 3.20 or greater
• For Gtk#2 (Eto.Gtk2): gtk-sharp2 package from your distribution

Notes:

• For Nuget packages to download properly on linux, you need to import the SSL root certificates using the mozroots --import --sync command.
• Cannot build WPF, WinForms, Xamarin.iOS, Xamarin.Android, or Xamarin.Mac applications
• Can build and package MonoMac applications, but not run them

• Mono
• .NET Core SDK
• Visual Studio Code
• Mac only (optional): Xamarin.Mac

Notes:

• Can only build/run WPF and WinForms applications on Windows
• Can only build/run Xamarin.Mac applications on macOS

To build you can use one of the solution files:

• Eto.sln - All projects for both .NET Framework and .NET Core
• Eto.Core.sln - .NET Core only projects

To build Eto.Forms and associated NuGet packages outside of your IDE, you can run the Resources/build.sh (mac/linux) or Resources\build.cmd (windows) scripts. You can also pass a parameter to these scripts to set the new version. E.g.

./build.sh 2.1.0 or build.cmd 2.1.0

Ensure your pull request builds and passes all checks. A check or X will show next to your pull request on github showing you the build status.
