dotnet

dotNet Protector is a powerful .NET code protection system that prevents your assemblies from being decompiled. With dotNet Protector, your application is not simply obfuscated, but merged in a Win32 native executable; Console exe, windows exe and windows services can be protected. You can protect a whole application (main exe, referenced dlls and resource localisation dlls) in a single executable.

dotNet Sniffer is a small utility that scans managed processes for .Net assemblies loaded from memory and lets you save them to disk.
