The loss of source codes is a very serious problem for many developers. From my personal experience I can say that it is indeed a terrible misfortune. Imagine you write the program, spend your force, time and money, release compiled program to the customers... But one morning you see that all your sources are gone (it may be your cat, or aliens. Who knows?) You are in panic. What should you do? Tear one's hair? There is no need. Just take the VB Decompiler and simply decompile your project! VB Decompiler restores the source code from the pseudo code (P-Code) as close as possible to the original. So, after some modifications you may get really workable source code.

Xamarin apps are built with standard, native user interface controls. Apps not only look the way the end user expects, they behave that way too. Xamarin apps have access to the full spectrum of functionality exposed by the underlying platform and device, including platform-specific capabilities like iBeacons and Android Fragments. Xamarin apps leverage platform-specific hardware acceleration, and are compiled for native performance. This can’t be achieved with solutions that interpret code at runtime.

paxInterpreter allows to execute intermediate paxCompiler byte-code. New runner is interchangeable with paxCompiler TPaxProgram class without any restrictions, i.e. you can use it with all pax components (TPaxCompilerDebugger, TPaxCompilerExplorer, TPaxEval), the same import routines allows you to import host-defined members. paxInterpreter supports the same scripting languages: Pascal, Basic, j@vascript.
