Reactor 0.1.0-preview.6

Reactor 0.1.0-preview.6

Interim distribution — see spec 022 for the rollout plan.

New in this release

Reactor.VsExtension.vsix — very rough, experimental live embedded preview for Visual Studio 2022. This is the roughest surface in the experimental Reactor repo; expect install friction, solution-load races, HWND/DPI edge cases, and breaking changes. Requires Windows 11 23H2+ and WinAppSDK 1.6+. See VS extension guide or src/vs-reactor/README.md. Phase 1 dev distribution may be unsigned.

Five assets

Microsoft.UI.Reactor.0.1.0-preview.6.nupkg — the framework

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

<!-- nuget.config -->
<configuration>
  <packageSources>
    <add key="reactor-local" value="C:\path\to\folder\with\nupkg" />
  </packageSources>
</configuration>

Then in your .csproj:

<PackageReference Include="Microsoft.UI.Reactor" Version="0.1.0-preview.6" />
<PackageReference Include="Microsoft.UI.Reactor.Advanced" Version="0.1.0-preview.6" />

Microsoft.UI.Reactor.Advanced.0.1.0-preview.6.nupkg — optional Win2D/advanced controls

Versioned in lock-step with the framework package.

Microsoft.UI.Reactor.Devtools.0.1.0-preview.6.nupkg — optional devtools host (debug + VS preview)

Referenced by the scaffolded dotnet new reactorapp csproj in a
Debug-only ItemGroup, paired with RuntimeHostConfigurationOption Reactor.DevtoolsSupport=true. Required to light up the right-click
devtools menu in Debug F5 launches and for the Reactor VS embedded
preview extension's embed-host activation. Versioned in lock-step
with the framework package.

reactor-skill-kit-0.1.0-preview.6.zip — agent skill bundle + mur CLI

Extract, then run:

cd reactor
.\install-skill-kit.ps1

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

Reactor.VsExtension.vsix — Visual Studio 2022 embedded preview

Double-click to install per-user, or install into the Experimental hive for smoke testing. This VSIX is intentionally rougher than the rest of the release assets and should be treated as an experimental feedback vehicle, not a stable workflow. See src/vs-reactor/TESTING.md before release promotion.
