This Mac sample is quite useful for authoring and viewing Markdown files, but also offers a little insight into building a hybrid web and native Mac application.

• MonoMac.AppKit.NSDocument is used for automatic document handling.
• The MonoMac.WebKit.WebView control is used for rendering.
• File system monitoring through MonoMac.CoreServices.FSEventStream is used to monitor the loaded document for changes.
• Changes made are reflected by replacing content directly in the DOM.
• JavaScript is used to scroll the page, invoked from native code.
• Navigation events are intercepted to open links in the system browser.

The Sundown C library is used to actually convert Markdown to HTML. In addition all the Github extensions are enabled. A small C# binding to Sundown is included.

• Learn Github Flavored Markdown
• Become familiar with classical Markdown
