I am new to Xamarin Android. I have created an App using Visual Studio 2015 Community Edition. I have set the Solution Configuration to Release.
For obfuscation I used .
It has come extremely easy to use .net reactor with xamarin today:
from reactor ide install extension for your visual studio appropriate version (menu Visual Studio)
in reactor ide create a project for your xamarin solution. You can use menu "Protection Themes->Xamarin" or play with you own settings. Do not forget to add additional files (your Forms shared project and others needed). save project, note its path.
in Visual Studio ide menu Tools->Reactor Automation set:
Click ok, that's it.
The build process would be MSBuild compiling, then reactor would apply its processing, then VS would pack/aot whatever was set for platform deployment/distribution.
