Three assets

Microsoft.UI.Reactor.0.1.0-preview.2.nupkg — the framework

Drop into a folder and add a NuGet source pointing at it:

Then in your .csproj:

Microsoft.UI.Reactor.Advanced.0.1.0-preview.2.nupkg — optional Win2D/advanced controls

Versioned in lock-step with the framework package.

reactor-skill-kit-0.1.0-preview.2.zip — agent skill bundle + mur CLI

Extract, then run:

cd reactor
.\install-skill-kit.ps1

Installs to ~/.claude/skills/reactor/ and adds bin/ to your user PATH. After a new shell, mur --version should resolve.
