xnodeoncode · 2026-03-07T13:42:03Z

Upgrade ElectronNET, fixed issues with application path, and added runtime identifiers.

Copilot

Pull request overview

Upgrades the desktop packaging/runtime setup for Nine’s Electron-hosted Blazor app, including moving to ElectronNET.Core and adjusting publish/build configuration to better support OS-specific deployment.

Changes:

Replace ElectronNET.API package usage with ElectronNET.Core / ElectronNET.Core.AspNet and update Electron-related MSBuild properties.
Rework Electron startup flow in Program.cs (Electron “ready” callback) and simplify path handling to use OS user-data locations.
Add electron-builder config + publish profiles and update ignore rules for publish output.

This change makes the app Electron-only (always UseElectron, fixed URL binding to :8888, and always AddElectronServices) and removes the previous web-mode branching. The PR description only mentions upgrading ElectronNET and path/RID fixes; if web hosting is still a supported deployment, this is a breaking behavior change that should either be reverted or explicitly documented/guarded behind a config flag.

4-Nine/Shared/App.razor

-    <link rel="stylesheet" href="@Assets["Nine.styles.css"]" />
+    <link rel="stylesheet" href="@Assets["co.nineapp.nine.styles.css"]" />


The isolated CSS bundle name is typically based on the project/assembly name (defaulting to Nine.styles.css). This project file doesn’t set <AssemblyName>, so referencing co.nineapp.nine.styles.css is likely to 404 and drop component-scoped styles. Either set <AssemblyName> to match, or revert the link to the actual generated *.styles.css name.

+    "icon": "Assets/icon.icns",


The macOS build config points to Assets/icon.icns, but there is no icon.icns under 4-Nine/Assets/ in this repo (only icon.png and icon.ico). Packaging for macOS will fail unless an .icns is added or the config is updated to a file that exists.

Suggested change

"icon": "Assets/icon.icns",

"icon": "Assets/icon.png",

Linux extraFiles references Assets/co.nineapp.nine.appdata.xml, but the repository contains 4-Nine/Assets/com.nineapp.nine.appdata.xml (different prefix/path). Electron-builder will fail to copy this file unless the filename/path is aligned.

ElectronPackageId is set to co.nineapp.nine, but existing desktop metadata in the repo uses com.nineapp.nine (e.g., Assets/com.nineapp.nine.appdata.xml, and the added desktop-config.bk uses com.nineapp.nine). This inconsistency can break Linux metadata copying and app identity/update behavior; pick one identifier and make the configs/assets consistent.

4-Nine/Program.cs

    {
        app.Logger.LogWarning("Loading offline page due to backend unavailability");
        window.LoadURL($"{backendUrl}/offline.html");
    }


ElectronAppReady() never navigates to the main app when the backend health check succeeds. LoadURL() is only called for the offline page, so when isBackendReady is true the window will stay blank. Add an else branch (or unconditional default) to load the normal backendUrl (e.g., /) when the backend is healthy.

app.Logger.LogInformation("Backend is ready, loading main application");
