DotNet Resolver is a free .NET decompiler written in C#. This decompiler is able to read, translate and edit applications written in any .NET language. The application has been designed to be as stable as possible, and therefore it doesn't fail that fast when opening protected or obfuscated applications.
This project has been started after Red Gate, the company that owns the well-known decompiler .NET Reflector, announced that they would charge for it.
The creator of this application is TheUnknownProgrammer, which is also the creator ofAsmResolver, the open source assembly reader. In the earlier versions of DotNet Resolver, Androcir and Ethernal Five have been helping with the development and statistics. Also thanks to MaxXor for the web hosting.
