- 13. What is Mono?Open Source Project that provides a CLR compiler for .NET on non-Windows OSWeb Site: http://www.mono-project.com/Main_PageMost of the.NET framework exists in MonoHere’s what doesn’t exist: System.Management does not map to LinuxThere are no plans to implement WPFWindows Workflow is a future enhancementEntity Framework isn’t availableServer-SideOData is not available, because it depends on the Entity FrameworkCodeContracts have been implemented in an API, but only partial tooling exists.
- 14. What is MonoTouch?Funded and managed by NovellAllows .Net Developers to create native applications using C# that can compile and run on iOS devices (iPhone, iPod, iPad)In essence, it compiles .Net code into Objective-C compatible code.
- 15. How does it do it without violating the Apple Licensing Agreement?But it still won’t run Adobe Flash…April 2010 : “Third Party Tools are prohibited”Tech Republic’s Justin James said “…I believe that signing this agreement is about equal to selling your soul for a grilled cheese sandwich.”September 2010 : “Third Party Tools are not prohibited”
- 16. How much of MonoTouch matches .NET Framework?Most of the .NET 2.0 CoreLINQGenericsWCFADO.NET wrappers for SQLiteSilverlight 2.0 APIWraps iOS APIs
- 17. What doesn’t exist?JIT-less environment is restricted by the kernelEliminates CodeDomDRLReflectionMemory ManagementP/Invoke methods
- 18. Just-In-Time versus Ahead-Of-TimeApple DOES NOT allow Just-In-time Compiling (JIT).NET uses Just-In-Time Compiling (JIT) MonoTouch uses Ahead-of-Time Compiling (AOT)Ahead of Time Compiling is also known as Static CompilationAOT Compiling creates all the native code that JIT would normally generateLinks to runtime to create a single ARM processor capable native binaryIL code is stripped from the managed assemblies, leaving just metadata
- 19. Garbage CollectionManaged Code handles garbage collectionsObjective-C for iOS uses Retain CountsRetain Counts : Reference Counts : Memory Pointers != Dealloc PointersMonoTouch handles garbage collection Creates an “AutoRelease” pool for anything that exists on the main thread and any child threads
- 20. What do I need to do to get started with MonoTouch?Intel Based Genuine Macintosh“… MonoTouch is not supported when running on non-genuine Apple hardware (Hackintsoshes) or other OS X installations virtualized in violation of Apple's license agreement, as we're unable to perform any kind of quality assurance testing for these systems, or otherwise diagnose issues that might occur in these scenarios.” – www.monotouch.netLatest iOS SDKCurrently at 4.02 (as of March 2011)Apple Developer’s Account ($99 a Year)Familiarity with Apple’s Development Restrictions
- 21. Installing MonoTouchInstallation order is VERY IMPORTANT!Remember, RTFI!!!!http://monotouch.net/Documentation/Installationat least OSX version 10.5.7 Leopard (OSX 10.6.6 Snow Leopard needed for iOS 4)Install iOS SDK Install Mono Framework (MonoDevelop is installed by default when Mono is installed)Install MonoTouchiPhone Configuration Utility from AppleDeveloper Certificates for testing on devices (simulator comes default)
- 22. Now is the time we Demo and Code!Getting Started You can’t escape the xibs!Drop controls on the Interface BuilderWire up the outlets in the AppDelegateAccess them from the C# Code Behind…Must use delegates, models and views…it’s the Objective C way.Virtual Machines…Visual Studio (2008\2010) via a VM (Virtual Box is free…) means you can use Visual Studio to handle coding using a familiar environment.Just make sure to map a reference path within the project to the directory that holds the Mono dll’s
