ilspy-vscode (powered by ICSharpCode.Decompiler)

Welcome to the ILSpy extension for Visual Studio Code! This extension provides two commands inside Visual Studio Code:

ilspy.decompileAssemblyInWorkspace - Decompile an MSIL assembly inside the current Visual Studio Code workspace.
ilspy.decompileAssemblyViaDialog - Decompile an MSIL assembly from file picker dialog.

Open the Visual Studio Code Command Palette (Ctrl+Shift+P) then type ilspy to show the two commands.

The Decompile IL Assembly in Current Workspace will put all potential .NET assemblies (files with extension .dll, .exe, .winmd, or .netmodule) in your workspace in a list for selection.

The Decompile IL Assembly (pick file) command allows choosing an assembly using the file picker dialog. The dialog should also allow one to type in the full path, for example, c:/temp/a.dll or /home/user/b.dll.

If the file is a valid .NET assembly, a tree view named ILSPY: ASSEMBLIES is added into the Explorer view. It allows expanding and selecting various nodes, whose decompiled C# code is shown in the editor.

Loaded assemblies can be closed by hovering the assemly nodes and clicking the "X" icon.

Further features are:

Symbol search across all loaded assemblies
Choosing decompilation language
Saving list of loaded assemblies along with currently open workspace

Requirements

Visual Studio Code >= 1.74
.NET 8.0 (installed automatically on first start)
