ILSpy is an open-source .NET assembly browser and decompiler that enables users to inspect and analyze .NET assemblies. With its user-friendly interface and powerful features, ILSpy is an essential tool for developers, security researchers, and anyone involved in reverse engineering .NET applications.
ILSpy was initially developed by Lutz Roeder and has since evolved into a collaborative project with contributions from developers worldwide. It is widely recognized in the .NET community for its reliability and effectiveness in decompiling .NET assemblies.
- Assembly Browsing: Navigate through the structure of .NET assemblies, including namespaces, classes, and methods.
- Decompilation: Convert .NET binaries back into readable C# code, allowing for code inspection and analysis.
- Search Functionality: Quickly search for types, members, and resources within assemblies.
- Plugin Support: Extend functionality with plugins that add custom features and capabilities.
- Windows, Linux, or macOS operating system
- .NET Framework (for running .NET applications)
- Basic understanding of .NET development and reverse engineering principles

ILSpy is primarily used for reverse engineering and analyzing .NET applications. Load a .NET executable or DLL, explore its structure, and view the decompiled code. The tool also provides options to export decompiled code to various formats.
- Code Analysis: Use ILSpy to examine the logic and structure of .NET applications, identifying potential vulnerabilities or areas for improvement.
- Decompilation Accuracy: Evaluate the quality of decompiled code and understand how it relates to the original source code.
- Assembly Resources: Inspect embedded resources within assemblies, such as images and configuration files.
- Unauthorized Use: Reverse engineering applications without explicit permission may violate software licenses and laws.
- Responsible Disclosure: If vulnerabilities are found in third-party applications, practice responsible disclosure to inform the developers.
ILSpy is a valuable resource for anyone working with .NET technologies. Its robust decompilation and browsing features make it a go-to tool for analyzing and understanding .NET assemblies. Always use ILSpy responsibly and ethically in compliance with relevant laws and regulations.
