Rhinocode CLI in RhinoWIP is unable to launch

Serengeti (Rhino WIP)

While running the latest WIP: “Version 9 WIP (9.0.25324.06306, 2025-11-20)”

This cli command has been running great until I did the recent WIP update…

$ /Applications/RhinoWIP.app/Contents/Resources/bin/rhinocode list --json
You must install or update .NET to run this application.

App: /Applications/RhinoWIP.app/Contents/Frameworks/RhCore.framework/Versions/A/Resources/RhinoCode.dll
Architecture: arm64
Framework: 'Microsoft.NETCore.App', version '8.0.0' (arm64)
.NET location: /Applications/RhinoWIP.app/Contents/Frameworks/RhCore.framework/Versions/A/Resources/dotnet/arm64/

The following frameworks were found:
  9.0.1 at [/Applications/RhinoWIP.app/Contents/Frameworks/RhCore.framework/Versions/A/Resources/dotnet/arm64/shared/Microsoft.NETCore.App]

To install missing framework, download:
https://aka.ms/dotnet-core-applaunch?framework=Microsoft.NETCore.App&framework_version=8.0.0&arch=arm64&rid=osx-arm64&os=osx.15

The message seems to indicate that an older .net framework is needed and possibly WIP is running a newer version? I did try doing the download and install of .net 8 before noticing that and it did not help.

Is this something for @eirannejad ?

After beating my head against it for a while, I threw the residue of human history at it (Claude Sonnet 4.5) and got it working…

11/24/25 - RhinoWIP rhinocode broken after update

Bug in RhinoWIP Nov 20 update: `RhinoCode.runtimeconfig.json` has mismatched versions - tfm is net9.0 but requests version 8.0.0, while RhinoWIP only ships .NET 9.0.1.

Fix:

```bash

sed -i ‘’ ‘s/“version”: “8.0.0”/“version”: “9.0.0”/’ /Applications/RhinoWIP.app/Contents/Frameworks/RhCore.framework/Versions/A/Resources/RhinoCode.runtimeconfig.json

```

May need to reapply after RhinoWIP updates until fixed upstream.

This was actually reported recently on Rhino 8 and I pushed an update to it. Make sure you are on latest Rhino 9.x

Thanks @eirannejad !

Looks like this issue either persists or has been reintroduced in:

Version 9 WIP (9.0.25343.14056, 2025-12-09)
Expires January 23, 2026

Just updated RhinoWIP to today’s latest (Mac) and it is still a problem:

Version 9 WIP (9.0.25350.00306, 2025-12-16)
