SecRandom → SecScore launcher plugin

A SecRandom plugin that adds a button to SecRandom's floating window. Clicking it opens or focuses the SecScore main window:

• If SecScore is running, its window is raised to the foreground (works even when it is closed to the system tray). Focus uses the Win32 AttachThreadInput workaround so a NoActivate floating window can still bring SecScore forward.
• If SecScore is not running, the plugin launches the executable. The path is user-configurable (Settings → SecScore) and auto-detected as a fallback (running process, Program Files, local user installs, and a sibling SecScore folder).

Windows-focused; on other platforms the button is a logged no-op.

Requirements

• .NET 10 SDK
• A sibling SecRandom source checkout at ..\SecRandom (the SDK is not published, so the plugin compiles against it from source). Override <SecRandomSourceDir> with -p:SecRandomSourceDir=... when using another directory layout.

Build

Because SecRandom.PluginSdk is not published to public feeds, the plugin compiles against the SDK from source (and therefore also SecRandom.Core + Avalonia/FluentAvalonia, so the first build is slow). Two prerequisites:

1. A .NET 10 SDK.
2. The SecRandom source checkout at the path in <SecRandomSourceDir> in src/SecScoreLauncher/SecScoreLauncher.csproj (default ..\..\..\SecRandom).

On a machine with an up-to-date Windows you can build directly:

dotnet build src/SecScoreLauncher/SecScoreLauncher.csproj -c Release

⚠️ Windows 10 CET workaround (this machine)

This machine's Windows 10 build ships ntdll.dll 10.0.19041.1566, below the 10.0.19041.5007 that .NET 10 requires for CET, and the CPU's CET shadow stacks are enabled. As a result the .NET SDK's native compiler apphost (csc.exe) refuses to start with Your Windows doesn't fully support CET. Running the compiler through the dotnet muxer (dotnet exec csc.dll) works, so build.ps1 points the MSBuild Csc task at a csc.cmd wrapper and sets DOTNET_EnableCETShadowStacks=0:

./build.ps1

Alternatively, fix the root cause on the OS: install the latest Windows Update (so ntdll.dll is >= 10.0.19041.5007), or disable CET shadow stacks in firmware/registry and reboot — then the plain dotnet build command above is enough.

Either way the installable package is produced at:

src/SecScoreLauncher/srpx/SecScoreLauncher.srpx

Install into SecRandom

1. Copy SecScoreLauncher.srpx into the SecRandom app's package folder:
   • Installed app: <SecRandom data folder>\cache\plugin-packages\
   • (Dev/portable: <SecRandom package root>\data\cache\plugin-packages\)
2. Restart SecRandom.

The button is not shown by default — enable it in Settings → Personalized → Floating Window, and switch the SecScore button on.

Configure the SecScore path (optional)

Open Settings → SecScore. Set the SecScore.exe path, or click 自动检测 (auto-detect) and then 保存 (save). Leave it empty to always auto-detect at launch.

How it works

• Plugin.cs — entrance (PluginBase) that registers a hosted service and a settings page.
• Services/SecScoreLauncherService.cs — hosted service that registers the floating-window button (FloatingWindowButtonDescriptor) via IFloatingWindowButtonRegistry.
• Services/SecScoreLauncherConfig.cs — exe path persistence (settings.json under the plugin config folder) and auto-detect.
• Win32/SecScoreWindowFocus.cs — FindWindowW("SecScore") → ForceForeground, else launch via Process.Start.
• Views/SettingsPages/SecScoreLauncherSettingsPage.cs — path editor.
