Assembly Obfuscation, integrated into Visual Studio
RemObjects Oxfuscator is a state-of-the-art obfuscation solution that integrates directly into the Visual Studio IDE and MSBuild compilation process, to let developers obfuscate their executables as part of the regular compile cycle.
Oxfuscator can process assemblies generated with C#, Visual Basic .NET, Delphi Prism or any other .NET language. It can be controlled and configured using Attributes inside the code, or via its project property pages within the IDE.
Get Oxfuscator and give it a go to see how useful it can actually be for you!
