Free .NET Reflector Alternatives to Decompile IL Code

While doing development applications with .NET we sometime require to decompile code to know how the code has been developed and for that we can use built in IL Disassembler but it just shows IL code. So many of the developers use .NET Reflector which is very powerful .NET decompiler. As .NET Reflector is not free many developers like me looking for free alternatives and after some search I have found some free alternatives which I am sharing below. Hope you will like it.  

JustDecompile

JustDecompile by Telerik is one of the free .NET decompilers which can be used as .NET Reflector alternative. Telerik claims it is one of the fastest decompiler and it decompiles code 10 times faster than other leading commercial decompilers. It has several features like below which makes it nice decompiler.

• Open API for everyone to create extension
• Easy Code Navigation
• Assembly Management
• Tabs for easy switching between different methods of assemblies.
• Create Visual studio project from a decompiled assembly
• Decompile referenced assemblies in a Visual Studio project using Visual Studio Extension
• Command Line Support
• Decompile an assembly after browsing to it in Windows Explorer
• Usage Analysis

You can try it here and let me know your experience in comment section below.

dotPeek

dotPeek is also free .NET compiler and giving nice competition to other available decompilers. It is developed by JetBrains (ReSharper tool is also developed by JetBrains). If you are using ReSharper then you will feel at home working with dotPeek as it provides ReSharper-like navigation and search, code insight, and keyboard shortcuts.

Below are the features of dotPeek

• .NET Assemblies to C# Code
• Find Usage if any symbol
• Navigation and similar features of ReSharper
• C# Code to Visual Studio Projects
• Easy view with File Structure
• Can identify local source code based on PDB files.
• Inheritance hierarchy from a specific type or type member
• Show/hide Compiler Generated Code
• Rich Assembly explorer

I have been using dotPeek and until now it is really nice with decompiling code as like Reflector.

You too can try it here and share your opinion about it in comment section.

There are some other free and open source tools available but I haven't tried them so just listing down below.

• ILSpy
• Dis#
• Dotnet IL Editor
