NAnt Tasks

The preferred way to develop applications with the Monobjc bridge is to use the MonoDevelop addins. But there are cases when it is not suitable: Continuous Integration, automatic bundling, etc.

In these cases, a script-based development process is to be used. One of the most used script-based environment is NAnt which is available with the Mono runtime. Monobjc provides a set of NAnt tasks that are targeted for OS X development.

Here is an example of NAnt script:

<?xml version="1.0"?>
<project name="Monobjc Application" default="build" basedir=".">
  <description>Monobjc Application Build File</description>

  <property name="build.dir" value="build" overwrite="false"/>
  <property name="dist.dir" value="dist" overwrite="false"/>
  <property name="app.name" value="SimpleCocoaApp" overwrite="false"/>
