Free Reflector / DotNet decompiler tools

Free Reflector

Below you can find free Reflector tools I’ve found / collected and others suggested.  They are alternatives to ‘Red Gate’s DotNet Reflector’.

I used to love Reflector, It was such a wonderful tool. I used to learn code and tricks from the original .Net code by reverse-engineering it. Since Feb 2011, RedGate took over Reflector and it’s not a free reflector anymore. I’ve come to a point where I need a new decompiler tool, I am ready for something new.

What is DotNet reflector / Decompiler tool?

From Wikipedia, the free encyclopedia

A decompiler is the name given to a computer program that performs, as far as possible, the reverse operation to that of a compiler. That is, it translates a file containing information at a relatively low level of abstraction (usually designed to be computer readable rather than human readable) into a form having a higher level of abstraction (usually designed to be human readable). The decompiler does not reconstruct the original source code, and its output is far less intelligible to a human than original source code.

Free Reflector tools

  • dotPeek – ‘dotPeek is a free-of-charge .NET decompiler from JetBrains, the makers of ReSharper and more developer productivity tools.’
  •  JustDecompile – ‘JustDecompile makes it easy to recover lost source code or peer into assemblies to discover the root cause of an external bug. Integrates with the powerful Visual Studio add-in, JustCode, for inline decompilation. Free for everyone, forever.’
  • CodeReflect – ‘DevExtras .NET CodeReflect is a simple yet advanced free .NET assembly browser/decompiler. It is a free alternative to Red Gate’s/Lutz Roeder’s .NET Reflector.’
  • ILSpy - ‘ILSpy is the open-source .NET assembly browser and decompiler. Development started after Red Gate announced that the free version of DotNet Reflector would cease to exist by end of February 2011.’

    The last sentence is not clear. Is it a free add-on to Reflector?

    Please add your comments / experience if you used one, or add new suggestions if you know of other good free reflectors.

    When I realized Telerik JustDecompile was spamming my decompiled codes of goto statements, I quickly send it to Junk in flavor of dotPeek

    dotPeek for the exact same file did not used a single goto. JustDecompile puts labels outside scope of goto statements…

    I believe the Telerik JustDecompile are just lazy boys and should give up to share such tool generating codes that horrible
