Our verdict on dotPeek
dotPeek is JetBrains’ free standalone Windows desktop tool for examining compiled .NET software. It decompiles .NET assemblies into C# or IL, opens DLL, EXE, and WINMD files, and helps developers investigate assemblies, recover source context, and debug third-party .NET code. Its audience includes developers who need to inspect compiled applications, understand dependencies, or move recovered code into a Visual Studio project.
Its strongest area is the depth of its .NET browsing and source-recovery workflow. dotPeek can browse assembly metadata, references, and dependencies; explore .NET assemblies loaded by running processes; and provide navigation, symbol search, usage search, and type hierarchies. It can fetch available source through PDB files and source servers, generate PDB files, and provide a symbol server for Visual Studio debugging. These capabilities give developers several ways to move from a compiled assembly toward readable code or useful debugging context.
The Visual Studio integration is central to its ecosystem fit. Decompiled code can be exported to Visual Studio projects, while the symbol server supports debugging compiled assemblies in Visual Studio. dotPeek is free, with no paid edition, which keeps the product straightforward for individual .NET investigation and source-recovery work. Its scope is narrower for teams working outside Windows or examining native code: the product is Windows-only and does not target native-code decompilation. Choose dotPeek when your workflow centers on Windows, .NET assemblies, Visual Studio, and source recovery. Choose an alternative when cross-platform operation or native-code support is essential.
