Every .NET developer needs a .NET assembly browser. We do not need such tool for everyday usage. But we need to take a look at an unprotected compiled .NET assembly sometimes. One freeware tool well-known in the field is not a freeware anymore and .NET coders need an alternative. Rustemsoft represents freeware Refractor .NET assembly browser and decompiler that should be good for your .NET development needs. Also Rustemsoft Skater .NET Obfuscator is equipped with .NET assembly browser and decompiler interface since ver5.0. Freeware and Demo versions of Skater .NET obfuscator include the fully functional .NET code browser interface. RustemSoft does not charge for the .NET assembly browser and decompiler. Rustemsoft does not plan to charge for that.
To run freeware Refractor .NET assembly browser and decompiler .NET framework 4.0 has to be installed.
