Obfuscation in Xamarin Projects

Question

As you know Xamarin projects are compiled into dot net dll assembly and it\'ll be pack into apk file and can be easily reflected by reflectors like DotPeek.

Answer 1

Dotfuscator has support for Xamarin and instructions are online (for Dotfuscator Professional or the free Community Edition) for how to integrate it. In essence, the process is:

1. Configure the build to run Dotfuscator via an AfterBuild target
2. Configure Dotfuscator:
   1. Specify the inputs
   2. Exclude things from renaming, as usual / as needed
   3. Only use Mono-compatible transforms (Pro-only)
3. Configure a Copy task or post-build event to copy the obfuscated binaries back to their original locations
4. Build, verify obfuscation, and test
