dotPeek

dotPeek is a free decompiler and assembly browser developed by JetBrains, primarily used for examining and exploring the contents of .NET assemblies. It allows developers to decompile compiled .NET code back into readable C# or other .NET languages, facilitating understanding, debugging, and analysis of third-party or legacy libraries where source code may not be available.

The tool supports a wide range of .NET formats, including DLL and EXE files, and provides a user-friendly interface for navigation and search within decompiled code. It features syntax highlighting, navigation, and code comprehension tools, enabling users to quickly locate specific classes, methods, or properties. Additionally, dotPeek integrates with Visual Studio, allowing for seamless exploration of assemblies directly from the IDE.

One of the key functionalities of dotPeek is its ability to generate PDB (Program Database) files, which contain debugging symbols. This capability enables developers to step through decompiled code during debugging sessions, improving troubleshooting processes for applications that lack original source code. The tool also supports exporting decompiled assemblies back to Visual Studio projects, making it easier to analyze or modify third-party components.

dotPeek is part of JetBrains' suite of development tools and is widely appreciated for its accuracy in decompilation and ease of use. It adheres to strict licensing terms, being freely available for individual and commercial use, while maintaining a focus on security and reliability for developers working with compiled .NET applications.

Overall, dotPeek serves as an essential resource for reverse engineering, debugging, and understanding .NET code, particularly in scenarios involving legacy systems or third-party libraries.
