You are a vendor of free .NET applications and you want to protect the code to maximum level so that nobody should be able to disassemble it? For this case Skater free .NET obfuscator is great software! RustemSoft is providing the Skater .NET obfuscator Light freeware edition available to you for free. You can freely obfuscate your .NET apps for free. It is fully functional! Free ware is software tool distribution where the author retains copyright of the software, but makes the program available to others at no cost, modify it and sell it in the future. It is typically distributed without its source code that prevents code modifications by its users. The Skater .NET obfuscator Light cannot be resold or re-distributed by third parties for profit. Freeware tools are mostly distributed with an end-user license agreement that allows its redistribution to some extent, for instance permitting users to send copies to friends. However there can be restrictions, such as limitations on its business usage. Most freeware licenses allow the software to be openly redistributed but not sold. Freeware differs from free software. The " free software" definition mostly refers to software that is free not only in a money expense but also in that there are no limitations on its usage including the rights to alter and modify its code and redistribute the modified copies. Freeware is also not the same like open source software is. The "open source software" definition refers to software source code that is made widely distributable for free and there are very minimal limitations on its use. Open source software is usually free of money charge and commonly is the same as the "free software". Freeware Skater .NET Obfuscator can discourage reverse engineering or software modifications by obfuscating all your methods/names/variables and replacing them with strings of random characters, making it difficult to make sense of the decompiled code and a labor intensive task to reverse engineer your .NET assembly.
