JustDecompile 2023.2.802.0

JustDecompile 是一套專為 .NET 開發者設計的反編譯工具，主要用途是從已編譯的組件中還原原始碼，或深入檢查組件內容以找出外部錯誤的根本原因。它最特別的地方在於能與 Visual Studio 外掛 JustCode 整合，直接在開發環境中進行內嵌式反編譯，省去切換視窗的麻煩。這套工具由 Telerik 開發，曾支援 .NET 2 到 4.5、WinRT Metadata 與 Silverlight 等多種框架，不過原廠已停止新下載與技術支援，現有用戶仍可繼續使用，但不會再有更新。以評分人數來看，它屬於開發者工具中的小眾選擇，評價普遍不錯但討論度不高。

這套軟體適合需要逆向檢視 .NET 組件、遺失原始碼想找回程式邏輯，或想理解第三方函式庫內部實作的開發者。與同類工具相比，它的優勢在於與 JustCode 的整合性，但劣勢是官方已停止維護，遇到新版本 .NET 或相容性問題時可能求助無門。替代軟體如 BlueStacks、Turbo C++ 等並非同類型工具，選用時需留意 JustDecompile 僅支援 Windows 平台、介面為英文，且免費授權但不再提供官方支援，下載前最好先確認你的專案環境是否仍在它的支援範圍內。

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.

Progress Software has discontinued new downloads of Telerik JustDecompile as of April 2, 2024. While existing users can continue using the product, it is no longer available or supported as part of the Progress Developer Tools portfolio.



The utility quickly loads the core framework assemblies for .NET 2, .NET 3.5, .NET 4, .NET 4.5, WinRT Metadata, and Silverlight.

JustDecompile's robust search method quickly pinpoints problems. With the addition of Full-Text Search, the search is even more comprehensive.

JustDecompile can create a Visual Studio project from a decompiled assembly. So you'll never lose another project.

FAQs

What was Telerik JustDecompile used for?
JustDecompile was a free .NET decompiler created by Telerik. It allowed developers to inspect compiled .NET assemblies (DLL and EXE files) and convert them back into readable C# code for analysis, debugging, or learning how applications work internally.

Is Telerik JustDecompile still supported?
No. Telerik has officially retired JustDecompile, and it is no longer actively developed or supported. The company announced the discontinuation as part of a broader restructuring of its developer tool offerings.

Can you still use JustDecompile today?
Existing copies may still run, but since the product is retired, it does not receive updates, bug fixes, or compatibility improvements for newer .NET versions. This limits its usefulness for modern development environments.
