MonoTouch 3.1.2


This fixes the following issues reported by some users:

  • Unable to have linked simulator builds
  • Erroneous messages in the simulator debugger when targetting iOS 4.1

NOTE: This release REQUIRES the latest iOS 4.1 SDK from apple and OS X 10.6


The Apple iOS SDK 4.1 release for the iPhone Simulator no longer includes the UNIX 2003 stubs for system calls.

Historically MonoTouch has tried to support the most several recent iOS SDKs in 1 package, but the change in the iOS SDK 4.1 Simulator has made this significantly more difficult as the iOS 4.0 SDK and iOS 4.1 SDK are now significantly different.

This release addresses the incompatibility with the iOS 4.1 simulator SDK by specifically compiling the simulator mono against the new SDK, rather than the lowest common denominator as we have historically done.

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.
