dotPeek
.NET DECOMPILER
Decompile .NET assemblies to C#
dotPeek is a free-of-charge standalone tool based on ReSharper‘s bundled decompiler. It can reliably decompile any .NET assembly into equivalent C# or IL code.
The decompiler supports multiple formats including libraries (.dll), executables (.exe), and Windows metadata files (.winmd).
Export decompiled code to Visual Studio projects
As soon as you’ve decompiled an assembly, you can save it as a Visual Studio project (.csproj). This can potentially save a lot of time if you need to restore lost source code from a legacy assembly.
Download source code and debug third-party code
dotPeek can identify local source code based on PDB files, or fetch source code from source servers such as Microsoft Reference Source Center or SymbolSource.
dotPeek can also perform as a symbol server and supply Visual Studio debugger with the information required to debug assembly code.
Navigation and Search
dotPeek inherits a lot of features from ReSharper. These include contextual and context-insensitive navigation, usage search, as well as different code structure and hierarchy views.
Find usages of any symbol
Use Find Usages to search for all usages of a symbol, be it a method, property, local variable or a different entity. The Find Results tool window lets you group usages, navigate between them, and open them in the code view area.
Jump to a type, symbol or anything
Whenever you put a caret on a symbol in the code view area, dotPeek offers a plethora of contextual navigation options that are all available via Navigate To drop-down menu.
Navigate to related code
dotPeek indexes all assemblies in your assembly list, as well as all assemblies that they reference, and provides features to quickly jump to specific code. For instance, Go to Everything allows searching for an assembly, namespace, type, member, or a recently opened file.
