This repo contains all files needed to build mono.dll & mono-2.0-bdwgc.dll with debugging support for Unity.

The master branch contains the original files. You have to check out the dnSpy branch to build everything. Use VS2017.

Supporting a new Unity version for Dummies

• Pull in the latest Unity mono.dll source code (either git pull if you have it or git clone https://github.com/Unity-Technologies/mono.git)
• Get this repo and make sure master and dnSpy branches are at the latest commit (git pull in both branches)
• Compile umpatcher in this repo
• Download and install the correct Unity editor version
  • https://unity3d.com/get-unity/download/archive
  • https://unity3d.com/unity/qa/lts-releases
  • https://unity3d.com/unity/qa/patch-releases
• Locate the compiled mono.dll & mono-2.0-bdwgc.dll files, eg.:
  • C:\Program Files\Unity\Editor\Data\PlaybackEngines\windowsstandalonesupport\Variations\win32_nondevelopment_mono\Data\Mono\EmbedRuntime\mono.dll
  • C:\Program Files\Unity\Editor\Data\PlaybackEngines\windowsstandalonesupport\Variations\win64_nondevelopment_mono\Data\Mono\EmbedRuntime\mono.dll
  • C:\Program Files\Unity\Editor\Data\PlaybackEngines\windowsstandalonesupport\Variations\win64_development_mono\MonoBleedingEdge\EmbedRuntime\mono-2.0-bdwgc.dll
  • C:\Program Files\Unity\Editor\Data\PlaybackEngines\windowsstandalonesupport\Variations\win64_nondevelopment_mono\MonoBleedingEdge\EmbedRuntime\mono-2.0-bdwgc.dll
• Get the timestamp stored in mono.dll's PE header
  • umpatcher --timestamp "C:\path\to\the\correct\version\mono.dll"
• Check out the correct version branch in the Unity mono repo, eg. if it's v5.4.3, the branch is called unity-5.4. Branches ending in -mbe use .NET 4.x assemblies.
  • Use git branch -a to see all remote branches
• git checkout unity-5.4 (or whatever version you need)
• git pull (make sure it has the latest stuff)
• gitk to start a UI
  • Find the closest merge by comparing the merge date with the timestamp reported by umpatcher above
  • Remember the commit hash, you'll need it later
• Run umpatcher again to patch the code and commit it to the dnSpy-Unity-mono repo
  • umpatcher 5.4.3 aa8a6e7afc2f4fe63921df4fe8a18cfd0a441d19 "C:\path\to\Unity-mono" "C:\path\to\dnSpy-Unity-mono"

Building mono.dll & mono-2.0-bdwgc.dll

• dnSpy-Unity-mono.sln (Unity with .NET 2.0-3.5 assemblies)

  • Use configuration Release_eglib
  • Use platform x86 or x64

• dnSpy-Unity-mono-V40.sln (Unity with .NET 4.x assemblies)

  • Use configuration Release
  • Use platform x86 or x64

Commit hashes

A few versions have the same hash. -mbe = MonoBleedingEdge branch (.NET 4.x assemblies).
