Decompiler Frontends

Aside from the WPF UI ILSpy (downloadable via Releases, see also plugins), the following other frontends are available:

Features

  • Decompilation to C#
  • Whole-project decompilation (csproj, not sln!)
  • Search for types/methods/properties (substring)
  • Hyperlink-based type/method/property navigation
  • Base/Derived types navigation, history
  • BAML to XAML decompiler
  • Extensible via plugins (MEF)
  • Check out the language support status

How to build

Windows:

  • Check out the repository using git.
  • Execute git submodule update --init --recursive to get all required submodules.
  • Use ILSpy.sln to work.

(Optional, Windows-only) Note: If you want to use the same build configuration as the build server, you will have to install VC++ 2017 version 15.7 v14.14 latest v141 tools (or similar) from the "Individual components" section in the Visual Studio Setup. We use editbin.exe to modify the stack size used by ILSpy.exe from 1MB to 16MB, because the decompiler makes heavy use of recursion, where small stack sizes lead to problems in very complex methods.

Unix:

  • Check out the repository using git.
  • Execute git submodule update --init --recursive to get all required submodules.
  • Edit \ICSharpCode.Decompiler\ICSharpCode.Decompiler.csproj Add Sdk="Microsoft.NET.Sdk" to the Project element. This is required due to a tooling issue on Unix. Please do not commit this when contributing a pull request!
  • Use Frontends.sln to work.
