The announcement got a huge applause at Build today. And Xamarin Studio for OS X will now be free as a Community Edition for individual and small teams, officials said today. Microsoft also plans to make Xamarin's enterprise capabilities as part of Visual Studio Enterprise and Visual Studio Professional for no additional cost, company officials said on March 31, during the Day 2 Build 2016 developer conference keynote. apk.Microsoft is planning to open source the Xamarin software development kit, runtime, libraries and command line tools. This property is ignored unless the $(AotAssemblies) MSBuild property is True.Ī boolean property that determines whether or not assemblies will be Ahead-of-Time compiled into native code and included in the. Support for this property was added in Xamarin.Android 5.1. Note: Testing is key, having a complete app test suite and internal instrumentation for collecting runtime performance is key to getting those 5 stars reviews on the app stores -)Ī boolean property that determines whether or not LLVM will be used when Ahead-of-Time compiling assemblines into native code. In terms of optimization of AOT code, enable LLVM along with AOT in your release builds for performance/instrumentation testing. This means that certain programs might run slower as the generated code is more general than the specific code that the JIT can produce.Įnable LLVM and AOT for testing your release builds: Note: This is particularly useful for large programs that might need to execute a lot of code before they are operational. I've been using Mono (AOT w/ & w/o LLVM) for many years and you really need to instrument and test on your code.Īlthough the JIT mode is very fast, and the default optimizations in Mono have been tuned to provide a good balance between optimizations and JIT speed, AOT compilation provides a few extra benefits: I say should due to the fact that AOT'ing does not guarantee that you will see a faster execution time of a particular portion of code, it does eliminates the jitter, but there are lots of other factors involved.

Now, if you are doing X amount of work that is CPU bound within your code, say within the OnCreate (which you really should not be doing), you would (should) see a decrease in total time. AOT'ing your assemblies/code is not going to change the startup of the app's initialization (native app bootstrap + Xamarin/Mono initialization BUT not including any of your code execution time).
