In addition to the Mac section of there are three great sources of documentation that can also be of assistance with Xamarin.Mac questions:

  • Xamarin.iOS documentation - For many APIs (primarily outside of AppKit/UIKit) there are only small differences between the iOS and macOS versions. In some cases where a given iOS API has a name of UIFoo, a similar API named NSFoo can be found on macOS. These examples will be generally in C# already.

  • Apple’s Mac Dev Center - Many times an example of what APIs to call in Objective-C can be converted to C# in a straightforward manner. See Understanding Mac APIs for details on how to do this.

  • Stack Overflow - A great resource for simple one off questions such as "How do I auto expand all nodes in an NSOutlineView". These examples will often be in Objective-C and need to be converted to C#, but there is a subset of answers in C#.

User Interface

When working with C# and .NET in a Xamarin.Mac application, the Developer has access to the same User Interface controls that a developer working in in Objective-C and Xcode does. Because Xamarin.Mac integrates directly with Xcode, the developer can use Xcode's Interface Builder to create and maintain an app's User Interfaces (or optionally create them directly in C# code).

The guides listed below give detailed information about working with OS X UI elements in a Xamarin.Mac application:

Xamarin Workbook

If it's not already installed, install the Xamarin Workbooks app first. The workbook file should download automatically, but if it doesn't, just click to start the workbook download manually.
