Thanks to the guys at Eziriz, the latest build of FinalBuilder now has a .NET Reactor action.
https://www.finalbuilder.com/downloads/finalbuilder/550/FB550_297.exe
The .NET Reactor action enables you to automate protection/licensing of your .NET assemblies using .NET Reactor.
.NET Reactor is a powerful code protection and software licensing system for software written for the .NET Framework, and supports all languages that generate .NET assemblies.
.NET Reactor prevents decompilation by a variety of methods which convert your .NET assemblies into processes which no existing tool can decompile ( and which are also very likely to prevent decompilation by any future tool). .NET Reactor builds a native code wall between potential hackers and your .NET assemblies by producing a file which cannot be understood directly as CIL. Because the CIL in your assembly is emitted intact only at run time or design time (in a form in which the source is completely inaccessible), no tool is capable of decompiling .NET Reactor protected assemblies.
