Obfuscar is a basic obfuscator for .NET assemblies. It uses massive overloading to rename metadata in .NET assemblies (including the names of methods, properties, events, fields, types and namespaces) to a minimal set, distinguishable in most cases only by signature.

To install Obfuscar, run the following command in the Package Manager Console

Install-Package Obfuscar -Version 2.1.1
