• What is JustDecompile?

  JustDecompile is a free tool from Telerik for .NET assembly browsing and decompiling. It lets you take an existing compiled assembly (.dll or .exe) and easily browse the symbols it contains, and then just as easily decompile the assembly language back to readable C#, VB and IL. JustDecompile is a standalone tool and it does not require Visual Studio.

• Is JustDecompile an open source tool?

  While JustDecompile is free, it is not open source. It is available from Telerik free-of-charge for perpetual use (there are no "time bombs" in the software).

  JustDecompile is built on Microsoft's Managed Extensibility Framework, which provides a familiar model for creating and adding plug-ins to JustDecompile. In fact, JustDecompile's core features, like Find Usages and History Navigation, are simply plug-ins.

  Yes. We have "Create Project" from decompiled assembly functionality which works only for C# for now. You can find more information about it here.

  No, you cannot decompile obfuscated code with JustDecompile. We will gauge interest in adding this feature in the future and consider adding support at that point. For now, this is not on the immediate roadmap.
