All the features to
peer inside and see
how stuff works.
Fast code navigation
JustDecompile goes beyond simple search boxes and provides dialogs to quickly navigate to code symbols and types. Simply type the name of the object you’re looking for, or take advantage of the CamelCase search.
Create visual studio projects
JustDecompile can create a Visual Studio project from an assembly in order to export lost projects or obtain multiple classes without the need to copy and paste code. At present, JustDecompile is able to export decompiled code only to C#.
You can save resources from assemblies by right clicking on the desired resource and saving it.
Easy assembly management
Getting the assemblies you want to browse loaded has always been more difficult than it should be! JustDecompile finally does it right. You can quickly load the core framework assemblies for .NET 2, .NET3.5, .NET 4, .NET 4.5, WinRT Metadata and Silverlight with a single click.
You can also create your own custom Assembly Lists so that you don’t have to load the same assemblies times and times again.
Zip file distribution
JustDecompile can now be downloaded as a ZIP file. You can put the files on a USB drive for easy access without installation, or you can put them on a server so others can decompile from their workstation.
Visual studio inline decompilation
JustDecompile is part of the powerful Visual Studio productivity add-in JustCode. This integration allows you to decompile your project references directly inside Visual Studio. For more info, please watch this video.
Command line support
JustDecompile has the ability to export code directly from the command prompt. For ease of use you can add %PROGRAMFILES(X86)%\Telerik\JustDecompile\Libraries to your Path environment variable.
To generate Visual Studio project for an assembly from the command prompt, use the command JustDecompile.exe [/lang:csharp] /out:[OutputDirectory] /target:[PathAndAssemblyName]. This feature currently supports only C#, but in the future the /lang switch will enable you to target other .NET languages as well. Comments (if available) will be added to the code in the generated project by default. You can change this behavior by using the [/nodoc] parameter.
The JustDecompile Explorer context menu allows you to decompile an assembly after browsing to it in Windows Explorer, without having to open JustDecompile from the start menu.
The Find Usages features will bookmark the usages of the currently selected code symbol in any of the loaded assemblies.
Silverlight XAP decompilation from URL
The Silverlight XAP decompilation works from both your local file system and the web. To open a Silverlight file hosted on a website, select the Open menu and choose XAP URL.
You can Type in a URL to a public address that contains a XAP file (e.g.http://bookshelf.silverlight.bg). JustDecompile has no problem decompiling a Windows XAP file either. To test out this functionality, use Open… | File(s)… instead of XAP URL.
Create your own plugin and let JustDecompile help you even more. The JustDecompile API is open and documented. Also we've added two JustDecompile plugins: Reflexil, for assembly editing and De4Dot, for deobfuscating obfuscated assemblies. Find out more on our extensions page.
C#5 (WinRT) support
JustDecompile is following all new developments in the .NET world and has added support for the new version of C# and the Windows Runtime cross-platform application architecture on Windows 8 (WinRT).
APPX and WinMD support
Alongside WinRT support, JustDecompile now supports two new file formats Appx (which is used for packaging Windows 8 apps) and WinMD (WinRT meta data files).
