Dotfuscator is a tool performing a combination of code obfuscation, optimization, shrinking, and hardening on .NET, Xamarin and Universal Windows Platform apps. Ordinarily, .NET executables can easily be reverse engineered by free tools (such as ILSpy, dotPeek and JustDecompile), potentially exposing algorithms and intellectual property (trade secrets), licensing and security mechanisms. Also, code can be run through a debugger and its data inspected. Dotfuscator can make all of these things more difficult. Dotfuscator was developed by PreEmptive Solutions. A free version of the .NET Obfuscator, called the Dotfuscator Community Edition, is distributed as part of Microsoft's Visual Studio. However, the current version is free for personal, non-commercial use only.
