A dnSpy extension to add WebAssembly support

dnSpy.Extension.Wasm

A plugin to add WebAssembly support to dnSpy.

Features

As of v0.1.0, this plugin only serves as a WebAssembly disassembler. It aims to mimic dnSpy's look and feel as much as possible.

More features are planned for the near future. A non-exhaustive list of some ideas:

• A decompiler
• "Find References" to search for usages of a method/global
• Renaming symbols and saving the edited .wasm file
• Tooltips for opcodes in the disassembler

Compatibility

This extension targets dnSpyEx v6.1.9 and is not tested with any other version or distribution.

Debugging

Run build.ps1 netframework in the dnSpy submodule using the Visual Studio developer powershell, then use the provided run command for JetBrains Rider.

If you don't use Rider, you can start dnSpy with the --extension-directory parameter to quickly load the extension.

Installation and more info

For more info regarding dnSpy extensions and their installation, see the README of my other extension, which is more up-to-date and complete.

dnspy.extension.wasm's Issues

Look into integrating with Cpp2IL

See: https://github.com/SamboyCoding/Cpp2IL

They seem to have support for "dumps only" for wasm. I should look into what exactly that means and if we can use that information. It'd be great if we could extract function names and load them in.

Crashes on some files in the wild

Tested with a .wasm file generated by Unity, I believe it crashed while trying to resolve function bodies.
